Implementation of Ternary Phase Amplitude Filters Using a Magnetooptic Spatial Light Modulator.

摘要

Ternary modulation can be achieved with a single SLM and improved correlation discrimination can be experimentally realized. The use of a ternary phase amplitude filter (TPAF) to improve the performance of binary phase-only correlators has been proposed, analyzed, and simulated. This communication describes the experimental implementation of simple TPAF using a 128x128 element SIGHT-MOD magnetooptic spatial light modulator (MOSLM).
