ABSTRACT:
A solid state aperture is formed with an optical system and an electrode system. In different embodiments, the optical system includes electrically-responsive attenuation members, e.g., black guest host liquid crystals, and electrically-responsive, polarization-rotation members, e.g., twisted nematic liquid crystals. The electrode system includes electrodes of electrically conductive, optically transparent materials which are applied to the optical system to define attenuation segments of a desired attenuation pattern.
