光学系统成象质量的评价和检验是应用光学中的一个重要组成部分,而光学传递函数(OTF)是最有效的评价方法之一,现已广泛应用于控制光学的设计过程及光学系统的检验。 本文研究了用CCD来测量光学系统的OTF。线性光学系统的OTF可由线扩散函数
Optical system image quality evaluation and testing is an important part of the application of optics, and optical transfer function (OTF) is one of the most effective evaluation methods, has been widely used in the control of optical design process and optical system testing . This paper studies the use of a CCD to measure the optical system OTF. The OTF of a linear optical system can be obtained by a line spread function
