Based on the coherent optical theory, we extend the fractional Fourier transform of first-order correlation to a fractional Fourier transform of second-order correlation. An optical system for implementing a second-order fractional Fourier transform was designed. As a numerical example, we investigate the second-order fractional Fourier transform for a single slit.
基于相干光学理论，我们将一阶关联的分数傅里叶变换扩展到二阶关联的分数傅里叶变换。设计了一种用于实现二阶分数傅里叶变换的光学系统。作为一个数值例子，我们研究了单缝的二阶分数傅里叶变换。
