一种新的gyrator变换的快速算法
A new fast algorithm for gyrator transform
摘要
Abstract
In order to study the application of gyrator transform in optical information processing, a new fast algorithm for calculating gyrator transform was proposed based on twice fast Fourier transform algorithm. Under the condition of dimensional normalization, the discretization of the gyrator transform was studied and the sampling intervals were obtained in space domain, Fourier transform domain and gyrator transform domain respectively. Thus, this new algorithm could avoid scale transform. Some numerical simulation experiments were carried out based on the algorithm and the simulation results were consistent with those reported in the corresponding references. This algorithm can be applied to study gyrator transform.关键词
