Universal liquid crystal adaptive aberration correcting retina imaging system

The invention belongs to the technical field of microscope imaging, relates to a high-order aberration correcting optical design for high-ametropia human eyes, and discloses a universal liquid crystal adaptive aberration correcting retina imaging system. An LCD screen is adopted for displaying a sighting target point light source, and the sighting target is designed into an E shape so that the self-adjusting effect of visibility is enhanced; and meanwhile, E-shaped micro displacement is easily controlled on the LCD screen so that the position of an imaging area can be quantitatively changed. Through the sign of a plurality of key devices, the universality of the liquid crystal adaptive system in fundus imaging is improved, the problem of difficult clear imaging of the fundus adaptive imaging technology under the condition of over 800-degree myopia or 200-degree astigmatism can be solved, and the system can acquire a high-resolution retina image on the human eye of 200-degree astigmatism.
