Abstract
Method for controlling the temperature of a thermally sensitive body (10) exposed to visible and near-visible radiant energy (14) through the use and control of an electric field imposed on a liquid-crystal based material (20) capable of having a cholesteric-nematic phase transition with pleochroic dyes (32) mixed within the liquid-crystal based material (20).
