光学镜头成像质量研究

Research on the imaging quality of optical lens

调制传递函数(MTF)是评价光学系统质量的重要指标,利用MTF曲线以及点光源的弥散斑2种方法测量主要像差分别为彗差、球差的光学透镜成像质量,运用ImageJ和ZEMAX软件进行数据处理和理论模拟,将理论和实验相结合,直观展示彗差和球差相关性质.

Modulation transfer function(MTF)was an important indicator to evaluate the quality of optical system.In this paper,two methods,the MTF curve and the point spread function,was adopted to measure the imaging quality of optical lens with mainly comatic aberration and spherical aberration.Using ImageJ and ZEMAX,the comatic aberration and spherical aberration of lens were shown directly by combining theory and experiment.
