摘要
随着光学信息处理的不断发展,傅里叶变换透镜的应用也日趋广泛.本文阐述了傅里叶变换透镜的性质及作用,主要研究了长焦距傅里叶透镜光学设计的特点,以及目前国内外在设计该类型透镜时常采用的结构形式:四组元对称或非对称双远距结构.为了能进一步缩短傅里叶变换透镜前后两焦点间的距离,使之小型化,本文尝试了一种新的结构形式,比起四组元双远距结构,在结构也较为简单的前提下,它不仅进一步缩短了两焦点间的距离,而且输入面、频谱面的象质均良好.
This paper discusses characteristics and functions of Fourier transform lens,and studieson design method of long focal length Fourier transform lens mainly.In order to reduce distance between the focal planes of long focal length Fourier transform lens,and can get a small scale one,a new lens system is described,which makes distance between the focal planes shorter,and also has simple structure,good image quality meanwhile.
