At least one embodiment of the present disclosure involves an image display system and an image display method.
In recent years, many commercial shows of holographic display are implemented in a quasi-holographic way, in which a projector or any other means is used to form an image of a light source after 45-degree refraction onto a phantom imaging film (e.g. a holographic film).
Essentially different from a pure holographic way, this quasi-holographic way is implemented with a film having both relatively high transmissivity and relatively high reflectivity. Although such a quasi-holographic display technology allows a viewer to get a feeling of some spatial effect, it is not really holographic, because when viewing the virtual images from the imaging in some angles, the viewer still cannot perceive holographic images having the same display effect as real scenes.

For example, the spatial light modulator comprises a liquid crystal light valve, a MEMS spatial light modulator, a digital micro-mirror device or an acousto-optic modulator.
For example, the holographic image acquiring device, the image synthesis device and the image reconstruction device are connected through networks.

In accordance with an example of the present disclosure, there may be disposed one or more holographic image acquiring devices 110, each of which is configured to acquire holographic image information of a scene (for example, a stage etc.). The image synthesis device 120 is configured to generate holographic image synthesis information based on the holographic image information obtained by the at least one holographic image acquiring device 110. The image reconstruction device 130 is configured to reconstruct a holographic synthetic image in accordance with the hologram image synthesis information.
The holographic image acquiring device 110 is used to acquire holographic image information of a scene. If there are multiple holographic image acquiring devices 110, each of them can acquire holographic image information of a scene.
As shown in
In accordance with an example of the present disclosure, the light source assembly 111 may emit a first light beam and a second light beam. Optionally, the light source assembly 111 includes a first laser 1111 emitting a primary light beam, which are split into a first light beam and a second light beam by a light splitting device with the first light beam being an object beam and the second light beam being a reference beam. The second light beam irradiates the scene, such as, a stage scene, a scene containing objects, a scene containing persons, etc. The second light beam may irradiate the scene directly or be guided to the scene by the optical assembly 112. In this way, the light exiting from the scene is incident on the image acquiring device 114 after interfering with the first light beam; the image acquiring device 114 converts the interference information into electrical signals to get holographic image information, which can be sent, by the image acquiring device 114, to a nearby image synthesis device 120 directly through a data line or to a remote image synthesis device 120 through networks.
The optical assembly 112 is used to guide, split, filter or otherwise process light in the holographic image acquiring device. For example, as shown in
Optionally, the optical assembly 112 may further include a filter for filtering of light rays if light rays in a certain band are to be filtered from the first light beam. For example, the filter 1123 in
Optionally, in order to change the diameters and divergence angles of the light beams, the optical assembly 112 may further include a beam expanding device. In order for light to be coupled into the receiving device as efficiently as possible, the optical assembly 112 may further include a collimating device. For example, the first beam expanding and collimating device 1124 in
Optionally, in order to guide the light beam to the scene after being expanded or converged by adjusting the optical path, the optical assembly 112 may further include one or more lens, reflecting mirrors or plane mirrors or any combination thereof as required by direction guiding in the optical path. For example, the reflecting mirror 1125 and the first lens 1126 shown in
Optionally, in order to determine the spectral bandwidth and the intensity of the exiting light beam, the optical assembly 112 may further use a slit at the emitting end of the light source assembly 111 to set an appropriate gap. Optionally, the slit may have the maximum width of 2 millimeter (mm). As a slit is a principle component in a spectroscope, a spectroscope may be used to design a slit applicable to the light source assembly 111. For example, as shown in
It is to be noted that, in optical paths of the first and second light beams, the above-mentioned optical assembly 112 may be added or reduced, for example, with respect to its lens set, reflecting mirrors or other optical elements based on requirements in a practical application so as to, for example, adjust directions or divergence angles of light rays.
The image acquiring device 114 is used to convert the interference information formed by the interference into electrical signals to get and send holographic image information to the image synthesis device 120. For example, the image acquiring device 114 may be implemented by a Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor (CMOS) imaging device. Both a CCD and CMOS can sense light and convert optical signals into digital signals.
As shown in
In accordance with another example of the present disclosure, the holographic image acquiring device 110 may generate an image in a way as follows. As shown in
As shown in
In accordance with an example of the present disclosure, the light source assembly 111 may emit a first light beam and a second light beam. The second light beam illuminates the scene. The second light beam may irradiate the scene directly or be guided to the scene by the optical assembly 112. In this way, the light reflected from the scene impinges on the holographic storage material 113 after interfering with the first light beam to store the holographic image information of the scene into the holographic storage material 113.
In accordance with another example of the present disclosure, in addition to the first and second light beams, the light source assembly 111 may also emit a third light beam. The third light beam is used to irradiate the holographic storage material and thereby an imaging beam will be generated and exit from the holographic storage material. The imaging beam impinges on the image acquiring device 114 to convert optical signals into electrical signals.
Alternatively, the light source assembly 111 includes a first laser 1111 and a second laser 1112. The first laser 1111 is used to emit the above-mentioned first and second light beams, while the second laser 1112 is used to emit the above-mentioned third light beam. For example, the light beam emitted by the first laser 1111 is split into the first light beam and the second light beam. Of course, the light source assembly 111 may optionally include three lasers emitting the first, second and third light beams respectively.
Alternatively, the light source assembly may only include the first laser 1111, and the primary light beam emitted from the first laser 1111 is split into a first light beam, a second light beam and a third light beam.
The optical assembly 112 is used to guide, split, filter or otherwise process light in a holographic medical apparatus. For example, as shown in
Optionally, the optical assembly 112 may further include a filter for filtering of light rays if light rays in a certain band are to be filtered from the first light beam. For example, the filter 1123 in
Optionally, in order to change the diameters and divergence angles of the light beams, the optical assembly 112 may further include a beam expanding device. In order for light to be coupled into the receiving device as efficiently as possible, the optical assembly 112 may further include a collimating device. For example, the first beam expanding and collimating device 1124 and the second beam expanding and collimating device 1128 in
Optionally, in order to guide the light beam to the scene after being expanded or converged by adjusting the optical path, the optical assembly 112 may further include one or more lens, reflecting mirrors or plane mirrors or any combination thereof as required by direction guiding in the optical path. For example, the reflecting mirror 1125 and the first and second lenses 1126, 1129 shown in
Optionally, in order to determine the spectral bandwidth and the intensity of the exiting light beam, the optical assembly 112 may further use a slit at the emitting end of the light source assembly 111 to set an appropriate gap. Optionally, the slit may have the maximum width of 2 millimeter (mm). As a slit is a principle component in a spectroscope, a spectroscope may be used to design a slit applicable to the light source assembly 111. For example, as shown in
It is to be noted that in the optical paths of the first, second and third light beams, the above-mentioned optical assembly 112 may be added or reduced, for example, with respect to its lens set, reflecting mirrors or other optical elements based on requirements in a practical application so as to, for example, adjust directions or divergence angles of light rays.
The holographic storage material 113 is used to store optical information. As shown in
The image acquiring device 114 is used to generate data corresponding to the holographic image information, for example, to convert light rays into electrical signals. As shown in
As shown in
In addition, the light source assembly 111 may also emit a third light beam, which impinges on the holographic storage material 113 to generate an imaging beam exiting therefrom. The imaging beam impinges on the image acquiring device 114, which will generate electrical signal data corresponding to the holographic image information and then sends the data to the image synthesis device.
In accordance with another example of the present disclosure, the holographic image acquiring device 110 may generate an image in a way as follows. As shown in
In addition, in order for the optical information in the holographic storage material 113 to be read out, the second laser 1112 is used to emit light rays that are expanded and collimated by passing through the second slit 1127 and the second beam expanding and collimating device 1128 and are directed to the holographic storage material 113. The light rays exiting from the holographic storage material 113 pass through the second lens 1129 and impinge on the image acquiring device 114, which then converts the information stored in the holographic storage material 113 into electrical signals to be read out.
In order to reduce interference between multiple stored holograms as much as possible, it is enabled to record and read data in real time, and every time a holographic image is written in the holographic storage material 113, the holographic storage material 113 is rotated by an angle and then the next holographic image is written therein. In accordance with an example of the present disclosure, the holographic storage material 113 may be disposed on a movable device 115. When the image display system 100 is in operation, the movable device 115 can move the holographic storage material 113 to make the information of the light reflected from the scene 150 and having interfered with the first light beam recorded therein at different angles and positions and the holographic storage material 113 is irradiated by the third light beam to enable the data to be read out in real time.
Alternatively, the position at which the third light beam is emitted may change around the holographic storage material 113. For example, the second laser 1112 is disposed on a movable optical platform, which can drive the second laser 1112 to move round the holographic storage material 113, so that the emitting position of the third light beam may change around the holographic storage material 113.
Optionally, the movable device 115 is a rotatable table. For example, the rotatable table may be a single-axis rotatable table, a two-axis rotatable table, a three-axis rotatable table or a rotatable table with more axes. A multi-axis rotatable table is beneficial to improving the accuracy of the orientation of the rotatable table and the holographic storage material 113 disposed thereon and to storage and reading of holographic images.
As shown in

Optionally, in order to determine the spectral bandwidth and the intensity of the exiting light beam, the optical assembly 112 may further use a slit at the emitting end of the light source assembly 111 to set an appropriate gap. The slit may have the maximum width of 2 millimeter (mm). As a slit is a principle component in a spectroscope, a spectroscope may be used to design a slit applicable to the light source assembly 111. For example, as shown in
It is to be noted that, in optical paths in the present example, the above-mentioned optical assembly 112 may be added or reduced, for example, with respect to its lens set, reflecting mirrors or other optical elements based on requirements in practical application so as to, for example, adjust directions or divergence angles of light rays.

In accordance with another example of the present disclosure, the holographic image acquiring device 110 may obtain an image in a way as follows. As shown in
In order to reduce interference between multiple stored holograms as much as possible, it is enabled to record and read data in real time, and every time a holographic image is written in the holographic storage material 113, the holographic storage material 113 is rotated by an angle and then the next holographic image is written therein. In accordance with an example of the present disclosure, the holographic storage material 113 may be disposed on a movable device 115. When the image display system 100 is in operation, the movable device 115 can move the holographic storage material 113 to make the information of the light reflected from the scene 150 and having interfered with the first light beam recorded therein at different angles and positions and the fourth light beam irradiates the holographic storage material 113 to enable the data to be read out in real time.
Alternatively, the position at which the fourth light beam is emitted may change around the holographic storage material 113. For example, the second laser 1112 is disposed on a movable optical platform, which can drive the second laser 1112 to move round the holographic storage material 113, so that the emitting position of the fourth light beam may change around the holographic storage material 113.
Optionally, the movable device 115 is a rotatable table. For example, the rotatable table may be a single-axis rotatable table, a two-axis rotatable table, a three-axis rotatable table or a rotatable table with more axes. A multi-axis rotatable table is beneficial to improving the accuracy of the orientation of the rotatable table and the holographic storage material 113 disposed thereon and to storage and reading of holographic images.

In accordance with an example of the present disclosure, when multiple holographic image acquiring devices 110 send their obtained holographic image information to the image synthesis device 120 respectively, the image synthesis device 120 receives the multiple pieces of holographic image information and synthesizes them into one image.
In an embodiment, the image display system may further include an editing data input device 140 configured for a user to input editing data. In this way, the image synthesis device 120 may also utilize the editing data to edit one or more received pieces of holographic image information, for example, to perform image segmentation, image recognition, image format conversion or other operations on the image information. Of course, it can be understood by those skilled in the art that the image synthesis device 120 may edit and synthesize the holographic image information it has received or only a part thereof. For example, the desired part is firstly obtained and extracted from the holographic image information and only the part is edited and synthesized so as to generate the holographic image synthesis information. When having generated the holographic image synthesis information, the image synthesis device 120 may send the information to the image reconstruction device 130 for reconstruction of a holographic image.

In this way, the image display system in the embodiment of the present disclosure may synthesize and reconstruct holographic images of different scenes into one scene image. Or three-dimensional images at different geographical locations or from different data sources may be synthesized into one and the same image.

A third light beam is emitted to irradiate the holographic storage material and thereby an imaging beam is generated and exits from the holographic storage material. The imaging beam impinges on one image acquiring device, which converts the optical signals into electrical signals to obtain the holographic image information. Optionally, the holographic storage material may be disposed on a movable device, which can orientate different parts of the holographic storage material to the light beam to impinge thereon. For example, the movable device may be a rotatable table.
Alternatively, in accordance with another example of the present disclosure, in a third way to obtain holographic image information of a scene, optical images of a scene are pre-stored in a holographic storage material, and a fourth light beam is emitted to irradiate the holographic storage material, so that an imaging beam exiting from the holographic storage material is generated and impinges on one image acquiring device, which then generates electrical signals to get the holographic image information. Optionally, the holographic storage material may be disposed on a movable device, which can orientate different parts of the holographic storage material to the light beam to impinge thereon. For example, the movable device may be a rotatable table.
In step S602, holographic image synthesis information is generated based on at least a part of the holographic image information of at least one scene.
