人眼像差测量方法研究

由于人们对视力矫正的需求,近几十年来人眼像差测量技术得到长足进步。目前已经出现了可以重建波前的测量波像差的激光追迹技术,同步像差仪,哈特曼-夏克传感器,塔尔博特传感器,阴影像差仪,视网膜仪,主观追迹技术以及直接评价人眼视觉质量的干涉测量技术及双程法。现回顾和描述了各种技术的原理,并做了比较,同时提出了眼像差研究的发展方向。

Research on human eye aberration measurements

The field of human eye aberration measurement is moving rapidly during the recent several decades,being driven by the desire to optimize vision following refractive surgery.Up to now,there have been techniques like laser ray tracing,simultaneous aberrometry,Hartmann-Shack sensor,Talbot sensor,crossed cylinder aberroscope,retinoscopy,spatial resolved refractometry which can reconstruct the wavefront;there are also techniques like interferometric and double pass method which directly measures the optical quality of human eyes.In this paper,all these methods are described and compared and the direction of their development is pointed out.
