Paper Abstract

A new technology of one-shot digital holography is developed for instantaneous recording of the complex-amplitude hologram for color three-dimensional images. Three holograms for different phases of the reference light are obtained both by spatially sampling an off-axis hologram and by interpolating sampled hologram data, and the complex-amplitude hologram is extracted from these three holograms. The one-shot holography is generalized for recording the hologram with the reference light having general phase distribution, and the limitation of bandwidth in one-shot holography is also discussed. Numerical simulation and optical experiment are carried out to demonstrate one-shot recording of the complex-amplitude hologram. Results show that fine color images with high resolution are reconstructed from the complex-amplitude hologram as a result of perfect elimination of the direct beam, the zero-order noise and the conjugate beam. The one-shot digital holography can make possible to record color images of the moving object by adopting RGB pulse lasers, and to reconstruct moving color images in real-time with the holographic display
