Sampling moiré is introduced as white light-color moiré. The experimental results show that the red and blue color images of the sampling moiré fringes have phase difference π relative to each other. The principle of color sampling moiré is derived assuming that the Bayer pattern-CCD array can be considered a combination of a bicolor red–blue grating and a green smooth plate. The moiré fringes created by the superimposition of the red–blue and a binary grating are simulated under the circumstances, where the binary grating is illuminated by red, blue, and white sources. The results of the simulation confirm that the red and blue sources moiré fringes have a phase shift relative to each other and that the gray-scale moiré fringes of the white source have smaller contrast than those of color sources. Simulation of the color sampling moiré shows results similar to the experiments except that the phase difference of π differs close to the image edges in the latter, due to the color aberration of the lens. It is indicated that sampling moiré can be used as color moiré without a color source or a color grating, with low cost setup.
