IMAGES OF COMPUTER-GENERATED HOLOGRAMS ACHIEVED BY MODIFICATION OF DETOUR PHASE

摘要

The detour phase method for the design of computer-generated holograms can be modified to achieve the reconstruction along various diffraction orders. A single hologram can be used to display two patterns of different intensities along two diffraction orders. This is achieved by the release of any requirement on the phase distributions of these patterns, thus leaving them as free parameters. Some algorithms make possible non-identical reconstruction along two different off-axis diffraction orders. The two reconstruction orders can be chosen arbitrarily. The case of reconstruction for different images, computer simulations and optical experiments were carried out to demonstrate the possibilities of the proposed approaches.
