Paper Abstract

Experimental liquid crystal 8-12μm infrared modulators have been fabricated and operated utilizing the cholesteric-nematic phase change effect occurring with cyanobiphenyl liquid crystals. A one mil thick film of 4-cyano-4'-pentyl-biphenyl has an average transmission over the whole 8-12μm region of ≈87%. Experiments to determine modulator response times and contrast are discussed as well as some of the basic limitations of infrared modulation using liquid crystals.
