建立了一套基于LCOS校正器的人眼像差自适应校正系统,并为该系统编写了一套完整的控制软件.该系统采用哈特曼波前探测器进行波面探测,将探测所得波前畸变经过PC计算处理后转化为灰度图,再通过PC把灰度图发送给LCOS上进行波面校正,通过校正人眼像差的方式来提高系统成像质量.经过实测,系统波前误差得到大幅度降低.实测表明,该系统的控制软件算法可以实现低阶大像差情况下人眼视网膜高分辨率成像.

In this paper,we present a liquid crystal adaptive optics(LC AO)retinal imaging system.A control software is written for the LC AO system.In the system,a Shark-Hartmann wavefront sensor is used to measure the aberrated wavefront.The measured aberrated wavefront is processed by a PC and is converted into a gray map,which is sent to LCOS to correct the aberrated wavefront.Thus,the quality of the retinal imaging is improved.Experiment results indicate that the proposed control software algorithm can achieve high resolution retinal imaging.
