失调光学系统衍射的分数傅里叶变换表述

THE DIFFRACTION OF MISALIGNED OPTICAL SYSTEM WRITTEN IN TERMS OF FRACTIONAL FOURIER TRANSFORMS

本文对一般的失调多元件光学系统衍射积分公式进行了整理分析 ,在空域和频域中分别引进缩放变量 。

The diffraction integral formulae in spatial-domain or frequency-domain are simply treated and analyzed in this paper.Under some conditions,the diffraction integral formula of a beam through a misaligned opticalsystem with multi-elements could realize the fractional Fourier transform by introducing scale variables.
