摘要 基于分数傅里叶变换的级联性,将变换级次由实数扩展到复数,获得了复数阶分数傅里叶变换的定义,推证了分数傅里叶变换的帕赛瓦尔定理,分析了其与吸收介质内部光传过程的等效性,诠释了复数阶分数傅里叶变换的物理机制,计算机模拟实验验证了结论的可靠性。 Based on fractional Fourier transform of cascade property, the optics real- order fractional Fourier transform can be extended to the optics complex - order fractional Fourier transform and then complex - order fractional Fourier transform Fourier transform definition is obtained, justifying Parseval s theorem of the fractional Fourier transform; we analyze the process' equivalent of light spread in the absorption medium and complex- order fractional Fourier transform, interp_reting complex - order fractional Fourier transform' physical significance. Computer simulation experiment results demonstrate the reliability.
