利用液晶空间光调制器和夏克哈特曼波前探测器作为核心器件搭建了一套开环双光源液晶自适应光学视网膜成像系统。系统采用人眼屈光0D基准设计并使用动态视标定位人眼，提高了人眼在测试时的稳定性，有效降低了由不同人眼个体差异带来的影响。通过补偿镜预补偿，配合微调照明光焦面，使照明光聚焦在眼底视觉细胞层，保证了像差探测精度和成像质量。利用人眼的偏振特性，采用偏振光照明的方式，将系统的能量利用率提高了20%。优化了系统的工作流程，优化后系统连续工作频率可超过20 Hz。对4名志愿者进行了实验，均获得了清晰的眼底视网膜细胞图像。

An open-loop adaptive optics system with liquid crystal spatial light modulator and Shark-Hartmann wavefront sensor is constructed. The system is designed according to zero diopter. Compared with the static target, the stability of the pupil increases obviously while staring at the dynamic target during the experiment. The impact of individual differences on human eyes has been reduced effectively. The focal plane of the light source can be axial shifted to ensure it can reach the photoreceptors layer of the retina with the help of trial lens. The fundus is illuminated by polarized light and the energy efficiency increases by 20%. The control flow of the system is optimized and the continuous working frequency of the system is above 20 Hz. Four volunteers are participated in the experiments. Both of them obtain the clear photoreceptor images after corrections.
