ABSTRACT:
A thermal imaging device uses a compensated cholesteric liquid crystal mixture as its thermo-optic conversion element. The mixture is obtained by mixing two cholesteric liquid crystals, one with a left-handed twist and the other with a right-handed twist. The twists cancel at a compensation temperature, the mixture thus having infinite twist at this temperature. The device is designed to operate with the mixture held in the region of the compensation temperature.
