白光彩色联合变换相关实验中的分通道方法

Discussion on the Channeling in the Experiment of Color JTC

提出了在彩色联合变换相关中， 使用光栅对彩色图像进行分通道处理的方法， 讨论了实现此方法对光源、滤色片的限制， 并基于此讨论提出了一种使用三色光栅图像编码的分通道解决方法。实验的结果表明， 这种方法不但降低了对光源的限制， 而且对取向不同的功率谱也便于进行分通道并行处理， 包括并行地使用零级功率谱进行彩色图像的仅形状相关。

The restriction on white light source and colour filter in a colour joint transform correlator (CJTC) is discussed. Based on this discussion, a new method of channeling using a three color grating for pattern encoding is suggested. It is concluded from the experimental result that, by using this new method, not only the restriction on the experimental condition is relieved, but also the power spectra of the encoded pattern are easy for experimental processing in parallel channeling. Besides, the zero order power spectrum forms an important channel for the shape only correlation.
