Abstract:
1. A Micromirror Array Lens with self-tilted micromirrors comprising a plurality of self-tilted micromirrors and configured to form a designed optical surface profile by self-tilted micromirrors to function as a lens, wherein each self-tilted micromirror comprises a) a substrate; b) at least one stiction plate configured to be attracted to the substrate by adhesion force; c) a micromirror plate having a reflective surface, coupled to the stiction plate elastically and configured to have a required motion when the stiction plate is attracted to the substrate; and d) at least one pivot structure disposed between the substrate and the micromirror plate and configured to provide a tilting point or area for the motion of the micromirror plate; wherein the designed optical surface profile determines the required motion of the micromirror plate and a surface profile shape memory is built in the self-tilted micromirrors so that each micromirror plate has the required motion.
