Human eye wavefront aberration detection system

Abstract

The invention provides a human eye wavefront aberration detection system, and relates to the technical field of optical imaging. The system comprises a fixation module, an illumination module, a scanning module and a detection module. The fixation module is used for fixing the fixation position of the human eye; the illumination module is used for generating parallel illumination beams; the scanning module is used for adjusting the direction of the parallel illumination beams, so that the parallel illumination beams are sequentially focused on a plurality of sites on the retina of the human eye, and generate a light wavefront signal after being reflected or scattered at each site; the light wavefront signal is returned by the human eye and the scanning module in the same way and then transmitted to the detection module; and the detection module is used for obtaining a point array distributed discrete spot map according to the light wavefront signal, the point array distributed discrete spot map is used for obtaining wavefront aberration information of the human eye, and the wavefront aberration information is used for establishing a retina refractive topographic map. According to the human eye wavefront aberration detection system, the detection efficiency of the refractive state and the optical performance of the human eye at different visual angles can be improved.

Description

technical field [0001] The present application relates to the field of optical imaging technology, in particular to a human eye wavefront aberration detection system. Background technique [0002] With the rapid development and popularization of electronic equipment, due to unhealthy eye habits or excessive eye frequency, parallel light rays cannot form a clear image on the retina after passing through the refraction of the human eye, resulting in Refractive errors, the formation of eye diseases, such as myopia, hyperopia, astigmatism and so on. Taking myopia as an example, pathological myopia can easily lead to retinal detachment, macular degeneration, glaucoma and other complications, which can lead to blindness. Therefore, it is very important to actively prevent and control myopia. [0003] Peripheral defocusing of the retina is an important factor leading to myopia. At present, the wavefront aberration technology has been gradually introduced into the field of evaluat...

Problems solved by technology

The general human eye wavefront aberration detection system needs to combine the moving fixation target, and detect the refractive state corresponding to multiple points on the retina by manual point-by-point measurement, so as to obtain the diopter of the human eye at different angles of view , this process requires the subject to cooperate with gazing at the visual targets at different positions, and the manual detection process takes a lot of time
