Paper Abstract

A new technology of one-shot digital holography is developed in order to record the complex-amplitude hologram for color three-dimensional images instantaneously. Off-axis RGB digital holograms are recorded with a color CCD at once, and three or four in-line holograms with different phases are obtained by spatially sampling the recorded holograms and by interpolating the sampled hologram data. RGB complex-amplitude holograms can be extracted for the reconstruction of color 3-D images from the RGB in-line holograms without any numerical calculation of digital filtering. Numerical reconstruction of images shows that fine color images with high resolution are reconstructed from the RGB complex-amplitude in-line hologram as a result of elimination of the direct beam, noises and the conjugate beam.
