Abstract
A method for modulating light using a micro-electro-mechanical structure includes providing a plurality of deformable mirror elements (30) having an L-shaped cross section. Each of the deformable mirror elements are comprised of a pedestal (32) and an elongated ribbon (33). Each of the ribbons has a reflective surface (35). A beam of light is directed on the deformable mirror elements. The deformable mirror elements is flexed about an axis parallel to a long dimension of the ribbons to vary a curvature of at least one of the reflective ribbons.
