Optically Addressed Light Valve

An optically addressed light valve suitable for selectively limiting the transmission of radiation from high intensity light sources independent of wavelength using a liquid crystal cell and a photoconductive material (vanadium doped silicone carbide). Originally designed to prevent ‘dazzle’ of light sensors its applications now include protection from sources such as sunlight, arc welding, head lights; or lasers.
