人眼像差的数学表示及主观式波前像差测量仪的设计与应用

本文详细介绍了一种新型主观式波前像差仪的工作原理,具体地阐述了主观式波前像差仪的光路控制系统、瞳孔自动跟踪系统以及计算机软件控制系统,并给出了像差仪的结构原理图以及程序控制流程图。同时介绍了主观式波前像差仪中用于定量描述波前像差的两种方法:Zernike多项式和波前像差图。主观式波前像差仪能精确地测量出人眼的低阶和高阶像差,其应用前景广阔。

Mathematical Expression of the Human Eye''''s Aberration and the Designing and Application of Subjective Wave -front Aberrometer

The paper introduces the working principle of a new subjective wave-front aberrometer and describes the control system of optical path、automatic tracing system of the pupil and computer program control system in a detailed way. The Schematic diagram of the aberrometer and the flow charts of program are illustrated. Two methods of wave-front aberration expressions, namely the Zernike polynomials and wave-front aberration maps,are also introduced. The aberrometer can measure lower-order and higher-order aberrations accurately. It will be widely used in the future.
