Flat diffraction grating light valve

The grating door modulates the incidence beams. Comprises an elongated elongate parts; each with reflection surface. Elongated elongate part of wherein an end aerosol, layer co-planer reverse. Guideposts staggered elongate part of the box, is received the first of. Integrated with the inserting finger elongated elongate part electrically coupled, and a second rod. By exerting first and second rod, each reflecting surfaces of keeps on the first plane. The full elongated elongate parts located on the first plane, the grating door as the light beam. The first elongated elongate part; the better is an image, the deformation, which is parallel to the main co-planer reverse on the first plane second plane. The first elongated elongate part group is arranged in the second plane, grating door a light beam.
