Paper Abstract

A phase-shifting holographic system for recording 3D color images is developed with a color CCD, and red (R), green (G), and blue (B) lasers. The phase of reference lights in this recording system is precisely shifted by moving the diffraction grating displayed on a high-resolution reflective LCD panel. Measurement of the phase shift of the diffracted light demonstrates the feasibility of the phase-shifting method. RGB in-line holograms can be recorded at the same time for a practical color object by adopting a high-resolution color CCD. Color images in the wide visual field are recorded by adopting a multi-channel CCD and are reconstructed from the recorded hologram by adopting a multi-channel LCD modulator. Holograms for reconstruction of RGB images are obtained from recorded in-line holograms by the phase-shifting holography, and fine color images of high quality are reconstructed from recorded phase-shifting holograms. The visual field or the viewing zone of the holographic system is enlarged by adopting a multi-channel color CCD and a multi-channel LCD panel.
