Digital White-Light Information Processing for Color Photography with Tricolor Grating

摘要

Digital techniques of white-light information processing for color photography with tricolor grating, the fusion of zero-order spectrum and integral atomic algorithm, are presented. The former remarkably improves the quality of decoding image by fusing the first-order spectra with the zero-order spectrum and the latter boosts the processing speed 60 times faster than the conventional technique using the discrete Fourier transform (DFT) only once and integral operation. The techniques make the digital white-light information processing practical in handling of photograph of huge size based on PC.
