Description

TECHNICAL FIELD

The present disclosure belongs to the technical field of sight systems, and in particular, relates to a sight system based on a fusion of infrared photography, low-illumination photography and an LED aiming light spot, and a sight with thermal imaging function.

BACKGROUND

The light emitted from an LED chip installed on the existing gun sight, after being reflected by a glued lens, forms an aiming light spot. The LED chip has a luminous band of 560±80 nm or other bands. The light emitted from the LED often contains a variety of colors such as red, yellow, green, etc., and the light containing the variety of colors is reflected by a narrow band interference filter film and a long-wave cut-off filter film coated on the glued lens and the light with a wavelength of 545±15 nm and a wavelength greater than 600 nm is reflected into the human eye, at the same time, the human eye observes the target and the environment around the target through the glued lens, and start shoots with an aiming means that the aiming light spot coincides with the target.

The patent application No. 201920048750.4 discloses an optical system of a reflective red dot sight that improves monochromaticity and concealment, including an LED chip and a lens used to reflect the light emitted by the LED chip. A filter coated with a narrow band interference filter film is arranged near the LED chip and between the LED chip and the lens. The filter is used to filter out light of a wider band other than the central wavelength emitted by the LED chip to improve the monochromaticity of the light entering the human eye. The light energy of the light with wavelengths other than the central wavelength emitted from the filter is weakened or cut off, and the energy of the light with the central wavelength emitted from the filter is illuminated on the glued reflective surface of the lens. The glued reflective surface is coated with a cut-off film that cuts off the central wavelength, so that when looking toward the lens from a long distance, the light emitted from the lens is not easy to be detected, thereby improving the concealment of the sight. In such a way of directly observing the target by the human eye, it is is very inconvenient or quite difficult to accurately judge or identify the target in a shooting environment with a long distance or poor lighting.

The patent application No. 201922462324.8 discloses a two-light three-color optical system and a sight thereof, including a green light chip module, a red light chip module and a right-angle prism. The green light chip module and the red light chip module are arranged vertically, and the geometric center of the cubic prism is set at the intersection of the emitting rays of the green light chip module and the red light chip module. The cubic prism is coated with a composite film on a diagonal surface extending along the angular bisector of the angle between the emitting light rays of the green light chip module and red light chip module. The composite film is used to completely reflect the red light emitted from the red light chip module and transmit the green light emitted from the green light chip module. Upon the provided two red and green light sources with emitting lights perpendicular to each other, by means of the prism, the total reflection film or the transmission film, green light, red light or yellow light or the like can be generated through the control circuit, which greatly reduces the number of light sources as well as the size and weight of the sight. However, this sight is still depend on a direct observation of target with the human eye, which is quite difficult to accurately judge or identify the target in a shooting environment with a long distance or poor lighting.

Embodiment 1

In order to solve the problem that the observation and identification of the target are greatly affected by ambient light due to the fact that the existing optical system of a sight requires the human eye to observe the target directly.

The present disclosure provides a sight system based on a fusion of infrared photography, low-illumination photography and an LED aiming light spot as shown in FIGS. 1-4, where the system includes an LED graphics chip 20, a lens 3, a beam splitter 30, a display screen 31, a thermal imaging core assembly 13, a low-light night vision camera module 48, and a main control board 51.

The light emitted by the LED graphics chip 20 and the light emitted by the display screen 31 both pass through the beam splitter 30 and are incident to the lens 3. The LED graphics chip 20 provides an aiming light spot under the control of the main control board 51. The light emitted by the LED graphics chip 20 is reflected or transmitted by the beam splitter 30 and then incident to the lens 3, the light is then reflected by the lens 3 and incident to the shooter's eyes 50. At the same time, the shooter's eyes 50 may directly observe the target 49 and the surrounding scenes through the lens 3. In addition, the thermal imaging core assembly 13 and the low-light night vision camera module 48 may capture video images of the target 49 and the surrounding scenes under the control of the control panel 1. The captured video images are played synchronously through the display screen 31. The images are incident to the lens 3 after being transmitted or refracted by the beam splitter 30, and are incident to the shooter's eyes 50 after being reflected by the lens 3. The source of the shooter's observation of the target 49 and the surrounding scenes may be the directly observed target 49 and the surrounding scenes, or it can be the video of the thermal imaging core assembly 13 and the low-light night vision camera module 48 projected by the display screen 31, thereby overcoming the problems of the existing sights that the observation is not clear and is greatly affected by environmental factors when the shooter directly observes the target 49 and the surrounding scenes through the lens 3. FIG. 4 is a schematic view showing the light path of the sight system based on the fusion of infrared photography, low-illumination photography and the LED aiming light spot. As can be seen from FIG. 4, the sight system is an of a reflective sight optical system, i.e., the light emitted by the LED graphics chip 20 and the display screen 31 are all reflected by the lens 3 and then enter the shooter's eyes 50.

The display screen 31 may use a Micro LED or an OLED. The thermal imaging core assembly 13 may use an Arrow's thermal imaging core assembly. The low-light night vision camera module 48 may use a SONY low-illumination 385 or 482 low-light night vision camera module. The main control board 51 is customized and developed according to the product requirements of using the LED graphics chip 20, the display screen 31, the thermal imaging core assembly 13, and the low-light night vision camera module 48. For example, a main control board model 21109 developed based on the LED chipset model HK-882, Micro LED, the thermal imaging core assembly from Arrow, Amap, etc., and the SONY low-illumination CMOS sensor may be used.

Further, depending on different application scenarios, the thermal imaging core assembly 13 and the low-light night vision camera module 48 as shown may be provided separately from the sight. For example, the images captured by the thermal imaging core assembly 13 and the low-light night vision camera module 48 may be directly transmitted to the sight or AR glasses in a wireless or wired manner, thereby improving the identifiability of the target and expanding the application environment of red dot sights. Users can freely choose to use the thermal imaging core assembly 13 or the low-light night vision camera module 48 with the sight according to their own application scenarios.

Two paths of light are reflected or transmitted by the beam splitter and then incident to the lens, and further incident to the shooter's eyes after being reflected by the lens. At the same time, the shooter can also directly observe the image of target and surrounding through the lens.

In this case, an OLED screen or Micro LED display is used, the beam splitter is not used, while two colors of LEDs of the OLED screen or Micro LED display screen are used, in which the green ones display the fused image and the red ones displays the divided image. The light emitted by the OLED screen or Micro LED display is directly incident to the lens, and is further incident to the shooter's eyes after being reflected by the lens. At the same time, the shooter can also directly observe the image of target and surrounding through the lens.

In summary, through the fusion of infrared photography, low-illumination photography and observation of the target with human eye, the sight system based on the fusion of infrared photography, low-illumination photography and the LED aiming light spot can assist in observing the target or identifying the same, and then determining the aiming target through an aiming light spot, so as to perform an accurate shooting.
