High efficiency optical reconstruction of binary phase-only filters using the Hughes liquid crystal light valve

Abstract

The Hughes liquid crystal light valve (LCLV) has been evaluated for its applicability in writing and reading binary phase-only filters (BPOFs) in optical correlators. Experimental measurements of relevant performance characteristics of the LCLV as well as experimental results demonstrating its use for reconstructing BPOF's are reported. We also find that this device allows a significant optical system throughput. In addition, we discuss generation of the BPOF with a MacIntosh computer system.
