Abstract

Current techniques for constructing multiple-phase-level structures (e.g., phase holograms) use computer-generated masks to selectively etch a glass substrate, creating discrete phase levels based on varying glass thickness (i.e., kineform). This approach requires several procedural steps and expensive photolithographic equipment. We have developed a one-step technique using color-printer technology and photographic eqipment. Colors from the printer are mapped to discrete intensity levels on photographic emulsion, and bleaching the recorded film results in discrete phase levels. We have investigated the relationship between the optical density of colors generated by our printer and the corresponding phase changes after bleaching.
