中文摘要：

建立了一套基于液晶波前校正器的模拟人眼眼底自适应成像系统，该系统采用Shark—Hartman波前探测器进行波面探测，将探测所得波前畸变经过计算处理转化为灰度图，通过电脑施加到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。经过校正后，系统波前误差从1．92μm降低到0．048μm，系统分辨率接近70lp／mm，已经达到该光学系统衍射极限分辨。研究表明，该系统可以满足低阶大像差情况下的模拟人眼视网膜成像要求。

英文摘要：

In order to get a better retina image and to correct the aberrations of human eyes, a model of eye adaptive optical imaging system based on liquid crystal was demonstrated. The Liquid Crystal On Silicon（LCOS） and HASO32 were used as a wave-front eorrector and a wave-front detector, respec tively, Then the wave-front aberration detected was calculated and converted into voltage value to correct the aberration by a computer on the LCOS. The optical performance of the model eye was improved by correcting the optical aberration of its own. After correction, the wave-front error is reduced from 1. 92μm to 0. 048μm in peak-to-valley, and the optical system diffraction limit is approached to 70 lp/mm,which shows the system has gotten a good image for the retina at a circumstance of low order and large aberration.
