FRACTIONAL FOURIER TRANSFORMS AND DIFFRACTION INTEGRAL FORMULA IN MISALIGNED SYSTEM
分数傅里叶变换和失调光学系统的衍射积分公式

Under some conditions the diffraction integral formula of a beam through a misaligned ABCD optical system in space domain could realize the fractional Fourier transform.And also,the diffraction integral formula in frequency domain for angle spectrum through a misaligned ABCD optical system could realize the fractional Fourier transform.At last,an optical system with a misaligned lens is given to illustrate its application.
