Abstract

Multiplex holograms can accurately represent 2-D space-variant optical systems if hologram-to-hologram cross talk can be reduced to an acceptable level. In the experiments reported here the combination of ground-glass diffusers with chirped wave front illumination proved to be an effective means of suppressing this cross talk. The residual cross talk distribution and intensity depend both on the signal and the optical system. The experiments also show that overlapping outputs from multiplexed holograms add coherently in amplitude. In addition, an accurate holographic representation of an extremely space-variant system is presented.
