Computer-generated true-color rainbow holograms

A new method of calculating computer-generated true-color rainbow holograms (CGTCRH) is proposed. This technique allows the true-color object reconstruction. The main idea of the presented work is based on the additive properties of holographic wavefront reconstruction such that the resulting hologram is a superposition of three (or more) holograms, with each of them producing different color reconstruction of the same object. White light and monochromatic light reconstruction results are discussed.
