The present invention relates to a synchronous orthogonal laser image reconstruction super-resolution microscope, and particularly relates to a rotary polarized laser image reconstruction microscope using a rotary polarized light apparatus.
Existing optical microscopes: due to the diffraction limit of light, a minimum display resolution size of the optical microscope is 0.2 micrometer, and due to the extremely low resolution, the optical microscope is inapplicable to a sample of a nanometer size and is more incapable of the imaging of atomic-scale samples; and although the resolution of a fluorescence microscope has been improved, the resolution has not been improved greatly, and fluorescence samples are needed for imaging, so the application range is limited.
Transmission electron microscopes: a resolution size of a transmission electron microscope with a spherical aberration corrector is 0.74 angstrom; the further increase of the resolution size requires the increase of acceleration voltage, which is easy to damage a sample; in addition, under the influence of the uncertainty principle, the resolution size is almost a display limit of the transmission electron microscope; moreover, the transmission electron microscope needs high voltage and complicated equipment, and is high in cost and large in electron energy, which influences measurement parameters of the sample; and high-energy electrons may damage the sample, and a large number of samples, such as biological live samples cannot be measured on site. Furthermore, scanning electron microscopes, atom tunnel microscopes and atomic force microscopes are limited in potential of improving the resolution.
Problems to be solved: the present invention aims at solving the problem that the existing optical microscope is low in image resolution due to the diffraction.
reconstruction of a synchronous orthogonal laser image: synchronous horizontal polarized laser rays and vertical polarized laser rays are alternately used to pass through a sample; when the synchronous horizontal polarized laser rays are magnified by a multilevel lens group to form a magnified real image, the formed image is subjected to spherical aberration correction by a spherical aberration correction component, and a magnified real image 1 is formed on an optical screen, a CCD, a CMOS or a crystal sensitive plate; then the synchronous vertical polarized laser rays pass through the sample and are magnified by the multilevel lens group, the formed image is subjected to the spherical aberration correction by the spherical aberration correction component, and a magnified real image 2 is formed on the optical screen, CCD, CMOS or crystal sensitive plate; the magnified real image 1 and the magnified real image 2 are subjected to the image correlation processing; the greater the correlation is, the greater the grayscale of the image point is; the weaker the correlation is, the smaller the grayscale of the image is; then the real image is filtered and reconstructed into a new super-resolution microscopic image; the horizontal polarized laser rays and the vertical polarized laser rays alternately and circularly pass through the sample, and a dynamic super-resolution image of the sample can be obtained by virtue of the image reconstruction;
reconstruction of synchronous multiple polarized light images: the synchronous polarized laser rays form a transmitted image whenever rotating by an angle (the rotating angle can be set, and a 360/rotating angular-amplitude image can be formed when the polarized light rotates in one circle); the images formed when the polarized light rotates in one circle form a group of (360/rotating angle) polarized light images; one group of polarized light images is subjected to image correlation processing through a computer to form a grayscale image according to the correlation strength; then the grayscale image is filtered and reconstructed into a super-resolution microscopic image; and the polarized light rotates circularly and is processed, thereby obtaining a super-resolution image of a dynamic sample;

A new observation means is provided for the biological on-site microscopic image observation, microscopic imaging of a chemical reaction bonding process, microscopic imaging of nano materials, etc. A resolution limit of the present microscope is a photon diameter, the photon diameter is not known at present but is ensured to be less than 10−15 meters. Since the photon has no rest mass, the influence of the uncertainty principle on the imaging accuracy of the photon microscope is much smaller, and the accuracy may be higher. The image resolution is increased by several orders of magnitudes compared with the existing electron microscope.
Although the implementation modes of the present invention are explained in combination with the drawings, those ordinary skilled in the art may make various variations or modifications within the scope of the appended claims and may also be a part of the present design.
