According to ocular aberration property and liquid crystal (LC) corrector characteristics, we calculated the minimum pixel demand of the LC corrector used for compensating large ocular aberrations. Then, an accommodation based optical configuration was introduced to reduce the demand. Based on this an adaptive optics (AO) retinal imaging system was built. Subjects with different defocus and astigmatism were tested to prove this. For myopia lower than 5D it performs well. When myopia is as large as 8D the accommodation error increased to nearly 3D, which requires the LC corrector to have 667 x 667 pixels to get a well-corrected image.
根据人眼像差特性和液晶（LC）校正器的特性，我们计算了用于补偿大像差的液晶校正器的最小像素需求。然后，引入了基于调节的光学配置以降低该需求。在此基础上构建了自适应光学（AO）视网膜成像系统。对具有不同散焦和散光的受试者进行了测试以验证这一点。对于低于5D的近视，该系统表现良好。当近视高达8D时，调节误差增加到近3D，这要求液晶校正器具有667×667像素才能获得校正良好的图像。
