| Abstract: | 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. |
