Fractional Fourier transform and the diffraction of any misaligned optical system in spatial-frequency domain

摘要

Relationships between the generalized diffraction integral formula for angular spectrum through any misaligned optical system in spatial-frequency domain and the fractional Fourier transform are bridged in this paper, which provides a new description of the diffraction of any misaligned optical system in spatial-frequency domain. Some special cases are also analyzed. (C) 2001 Elsevier Science Ltd. All rights reserved. [References: 25]
