摘要

目的:本文对一个用于人眼畸变波前探测和校正的自适应光学系统的性能进行测试和研究。方法:沙克-哈特曼波前探测器，高分辨率的液晶空间光调制器分别被用来探测和校正人眼的畸变波前。结果:对近视500度的人眼进行自适应校正后校正精度达到波前残差的均方根误差为0.013个波长（=0.808 nm）。眼底原来模糊的细胞可以被清晰分辨。结论:液晶空间光调制器可以有效校正人眼畸变波前，达到提高成像质量的目的。

Abstract

Objective: A adaptive optics system (AO) integrates human eye wave-front sensor components and correction components was built and tested. Method: The system uses a Hartman-Shack wave-front sensor (HS-WS) and liquid crystal spatial light modulator (LCSLM) for AO-correction of the dynamic aberrations of the human eye. Result: During testing with a 5D myopic human eye

the AO system corrected ocular aberrations to a residual RMS wave-front error of 0.013(=0.808 nm). Conclusion: The LCSLM can correct the aberration in eyes effectively

After AO correction the cone of the retina can be seen clearly.
