The restriction on white light source and color filter in a color joint transform correlator (CJTC) was discussed, then based on the discussion, a new method of channeling using a three-color grating for pattern encoding was suggested. The experimental results show that not only the restriction on the experimental condition can be relieved, but also the power spectra of the encoded pattern become easy for experimental processing in parallel channeling; besides, the zero-order power spectrum forms an important channel for the shape-only correlation.
