摘　　要：建立了基于Hartmann-Shack传感器的主客观人眼波前像差测量系统,该系统使用Hartmann-Shack传感器客观测量人眼像差,分别对模拟眼和活体人眼进行了像差测量.同时系统中加入了主观测量人眼像差的部分,该系统能够同时进行客观和主观的像差测量,实现了使用信息融合的方法对测量结果进行数据处理.并结合了客观测量和主观测量的优点,使用信息融合的方法使测量结果更加合理.A combined subjective and objective human eye wavefront aberration measurement system was established based on the Hartmann Shack sensor, which can survey human eye objective aberration. The model eye and the living human eye were measured, and both got fine results. In addition, the subjective view test in the system was added and the subjective and objective survey were enabled simultaneously. The system realized the data processing to the measurement result using the information fusion method,thus,it could combine the advantages of both subjective and objective measurements. The experimental results show that more reasonable results can be acquired in the measurement by this method.
