Abstract

A phase-shifting method by the SLM has been proposed for simultaneous recording of phase-shifted RGB holograms. The phase of RGB lights can continuously be shifted by adopting a LCD panel. A system with a high-resolution reflective LCD panel, a color CCD, and red, green, and blue lasers is developed for recording 3D color images. The phase of RGB reference lights is precisely shifted by moving the diffraction grating on a reflective LCD panel. Since a shifted value of the phase is independent of the wavelength of light in the present method, RGB interference fringe patterns for the practical object can be recorded at once by adopting a high-resolution color CCD. Fine complex-amplitude holograms for reconstruction of RGB images are obtained from recorded interference fringe patterns, and high-quality color images of the practical object are reconstructed from the holograms.
