人眼视网膜成像液晶自适应光学系统的优化设计

Optimal Design of LC Adaptive Optics System for Human Retinal Imaging

针对已有的人眼视网膜成像液晶自适应光学系统的不足,提出了新的优化设计方案.新设计的系统能对不同视度下的人眼进行高分辨率成像.新系统还采用了瞳孔监控装置和成像区域快速精确定位装置,并且采用了改进的消杂散光方法,能够使探测准确度和定位准确度得到保证.研究证明,该系统新的设计方案操作方便、灵活,便于推广使用.

Aiming at some weakness of the old LC adaptive optics system for human retinal imaging,a new design scheme is presented. The new system can obtain high-spacial-resolution retinal image for eye under different diopters. The pupil-monitoring system, imaging-orientation system are adopted to avoid stray light, which can make sure the precision of orientation and detection. The research results show that the new system is more convenient, more flexible and suitable for widely application and extension.
