Optical imaging system for detecting adaptability of cornea to AR equipment

Abstract

An optical imaging system for detecting adaptability of a cornea to AR equipment relates to the technical field of optical imaging system design. The problem that an optical imaging system for detecting the adaptability of different human eyes to existing AR equipment is needed is solved. The system comprises a first meniscus lens, a first doublet lens, a second doublet lens, an aperture diaphragm, a third doublet lens, a fourth doublet lens and a second meniscus lens which are sequentially arranged along the same optical axis. Light reflected by the cornea of a human eye is deflected by a corneal contact lens and then subjected to spherical aberration correction by the first meniscus lens, chromatic aberration elimination by the first doublet lens and the second doublet lens, beam limiting by the aperture diaphragm, chromatic aberration elimination by the third doublet lens and the fourth doublet lens and spherical aberration correction by the second meniscus lens, and then imaging isperformed. According to the invention, spherical aberration, coma aberration, astigmatism, field curvature, distortion, axial chromatic aberration and vertical axis chromatic aberration are small, and the imaging quality is high. Imaging cornea analysis can be carried out on different groups of people, and existing defects of AR glasses can be eliminated.
