分数傅里叶变换光学实现基本单元的参量选择

Parameter Selection of Base Unit in Optical Fractional Fourier Transform

以实现分数傅里叶变换的不等焦距双透镜模式为研究对象，分析了其与单透镜模式的等效性，给出了各种光学单元基本参量选择的判定法则。计算机模拟实验证明了结论的可靠性与可行性。

This paper describes the unequal focal distance double lens model in optical fractional Fourier transform.We analyse its equivalency with single lens models.A decision rule is presented,which describes the base prarmeterselection of optical system.Its reliability and feasibility are demostrated by compter simulation.
