Abstract
A system for modulating light using a micro-electro-mechanical structure includes 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.

A system for modulating light using a micro-electro-mechanical structure comprising:
- a plurality of deformable mirror elements having an L-shaped cross section;
- wherein each of said deformable mirror elements is comprised of a pedestal and an elongated ribbon;
- a reflective surface on each of said ribbons;
- a light source;
- and
- wherein said deformable mirror elements flex about an axis parallel to a long dimension of the ribbons to vary a curvature of at least one of the reflective ribbons and deflect a beam of light from said light source.
