Abstract: Infrared radiation is imaged on a film of liquid crystal whose characteristic color is a function of its absolute temperature. A heat exchanger in juxtaposition with the liquid crystal is provided for maintaining the ambient temperature of the liquid crystal at the temperature of maximum sensitivity to infrared radiation. A remote sensor responsive to the characteristic color of the liquid crystal controls the heating and cooling cycles of the heat exchanger. In consequence, the liquid crystal is maintained at the temperature of maximum sensitivity by remote sensing of color balance over the entire useful area of the film.
