Abstract
The wavefront printer is equipment for producing computer-generated holograms (CGH) as volume holograms. This printer records the wavefront generate by spatial light modulator (SLM). We use the phase-only SLM to generate the wavefront because of its wide space-band product. However, the phase-only SLM causes a problem of degradation of reconstructed images because of coding noise due to phase only modulation. This paper describes a technique to make complex amplitude modulation by using a phase-only SLM and ease the coding noise.
