TL;DR: In this article, the authors proposed an optical distometer based on SHACK-HARTMANN wavefront measuring principle, including a light source used to emit detection light, an array optical element for measuring the amplified wavefront variation, and a processing unit including a photoelectric conversion module for performing analysis process to the light of the array optical elements to obtain the distance of the measuring arm lens assembly and the corresponding eyeball.
Abstract: The utility model provides an optical distometer based on SHACK-HARTMANN wavefront measuring principle, including: a light source used to emit detection light, a light source lens assembly for emitting the detection light in the eyeball (109) to be detected, a measuring arm lens assembly for magnifying the wavefront variation of the detection light reflected by the cornea of the eyeball (109) to be detected, an array optical element for measuring the amplified wavefront variation, and a processing unit including a photoelectric conversion module for performing analysis process to the light of the array optical element to obtain the distance of the measuring arm lens assembly and the corresponding eyeball (109) to be detected. Compared with the prior technology, the utility model has the advantage that it can accurately determine the distance between the eyeball to be detected and the optical distometer when the portable optometry instrument is used to measure, and to further improve the detection accuracy.
