Abstract
We implement an optical continuous phase-only composite filter for security verification. An amplitude-mostly liquid crystal television (LCTV) is used for input and a phase-mostly LCTV is used for the phaseonly filter. We develop experimental techniques for optimizing the LCTV modulations and analyze the diffraction of both coupled-mode LCTVs. We use a new procedure for synthesizing the phase-only composite filters. The filter produces a narrow correlation peak without sidelobes. Experimentation results are shown.
