Colorimetry on pseudocolor-coded fringes of phase gradient

Using a single prism or a pair of reversed prisms, asymmetric or symmetric periodic pseudocolor-coding of the phase gradient fringes in both spectrum-diffraction interferometry and Fourier-filtering quasi-interferometry can be realized. In this paper, the loci of the chromaticity coordinates, the dominant wavelength, the luminance, the colorimetrio purity and the luminance in the dominant wavelength as a function of equivalent angles of refraction are calculated and analysed for all possible arrangements. The constrntion parameters for optimal color-coding are found exactly. Furthermore, a new ides for symmetric color-coding by two unoverlapped dispersions is suggested.
