摘要
利用球面波照射物体的自由空间菲涅耳衍射，完成任意级次分数傅里叶变换的无透镜光学实现，给出了不同条件下无透镜模式基本参量的选择法则及其分数傅里叶变换的数学表达。
In this paper,we describe the fact that arbitrary orders of fractional Fourier transform can be realized by the Fresnel diffraction in free space.In this case,the object should be illuminated by sphere light wave.We give out the select laws of the basic parameter under different conditions and the mathematic expression of the fractional Fourier transform.Its reliability and feasibility are demonstrated by computer simulation.
