Digital holographic printing using pulsed RGB lasers

摘要

A one-step digital holographic printing system based on RGB pulsed-laser technology is described. The system is capable of writing full-color composite digital reflection holograms and composite digital holographic optical elements up to a size of 1.0 m × 1.5 m at hogel sizes ranging from 0.4 to 2 mm. We also show how the same pulsed-laser technology may be used to generate fast high-quality copies of such holograms. Both silver halide and photopolymer materials are used.
