Abstract:

In Phase I, Physical Optics Corporations RD Division POC designed and developed a new Extremely Narrowband Cascaded Holographic Adjustable Range Tunable ENCHART filter using two holographic Fabry Perot filters HFPFs a coarse filter to select the desired portion of the optical range, and an extremely narrow 0.1 A bandwidth fine filter operating within this selected range at any arbitrary wavelength. The fine filter is an electrically tuned liquid crystal cell. All established objectives were exceeded and a proof of concept ENCHART prototype was fabricated. This technology was extended to and demonstrated in the violet blue region of the spectrum.
