Summary:Display systems employ a planar grating light-valve (GLV) array as a spatial light-modulator for representing an image to be displayed. The systems rely for image representation on the position of moveable reflective elements of the GLV array, which move through planes parallel to the plane of the array. The moveable elements provide, from an incident phase-constant wavefront, a reflected phase-modulated wavefront representing the image to be displayed. The displayed image is provided by interferometrically combining the phase-modulated wavefront with a reference wavefront also formed, directly or indirectly, from the incident phase-constant wavefront.
