设计了主客观方法相结合的人眼波前像差测量系统.该系统的控制部分以工控机为中心,实现了对离焦补偿装置、LCD视标显示装置和可变形镜驱动器的控制.使用Hartmann-Shack传感器对人眼出瞳的波前像差进行测量,光路中加入了能够显示各种视标和测试图案的LCD,从而考虑到了主观调节对人眼像差的影响,能够对人眼的视觉质量进行全面衡量,实现了客观测量和主观测量在光路中的结合.使用该系统分别测量得到了模拟眼和活体人眼的波前像差,并对主客观测量结果进行了信息融合,能够为个性化的人眼屈光矫正提供有用的依据.

A hybrid objective-subjective measurement system for human eye wavefront aberration is designed. The control part of the system adopts industrial computer as its controlling unit of focus corrector stage, LCD and deformable mirror. This system uses Hartmann-Shack wavefront sensor to measure wavefront aberrations of eye at the exit pupil. In optical part LCD which can display different optotypes is added, thus changes of ocular aberration with accommodation are considered. The system can comprehensive measure visual quality of human eye and combine objective measurement with subjective measurement. Wavefront aberrations of model eyes and human eyes are obtained from the system. Experiment results are treated by information fusion method. It can give more detailed advices for ideal customized refractive correction of human eye.
