THE DIFFRACTION OF MISALIGNED OPTICAL SYSTEM WRITTEN IN TERMS OF FRACTIONAL FOURIER TRANSFORMS
|
Abstract:
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.
