ABSTRACT:
A deformable membrane type of spatial light modulator may be modified and used with a lens for beam steering applications. A reflective membrane is deformed by one or more of a multiplicity of underlying address electrodes, such that it has a different center of curvature depending on which electrode is being energized. An incoming beam is incident on the membrane and reflected from it. A lens collimates light reflected from the membrane so that a beam is reflected in a desired direction relative to the incoming beam.
