The fractional Fourier transform is redefined for working with incoherent light. As a real transformation, the incoherent fractional Fourier transform overcomes coherent system disadvantages such as the speckle effect and the need for incoherent-coherent conversion. It also might have some applications for digital image and signal processing owing to its decreased computing complexity. An incoherent optical implementation of the new transform based on the shearing interferometer is suggested. Laboratory experimental results are given.
分数傅里叶变换被重新定义以用于非相干光。作为一种实变换，非相干分数傅里叶变换克服了相干系统的缺点，如散斑效应以及对非相干 - 相干转换的需求。由于其计算复杂度降低，它在数字图像和信号处理中也可能有一些应用。提出了一种基于剪切干涉仪的新变换的非相干光学实现方法，并给出了实验室实验结果。
