Abstract
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. Each self-tilted micromirror comprises a substrate, at least one stiction plate configured to be attracted to the substrate by adhesion force, 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 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. The designed optical surface profile determines the required motion of the micromirror plate and a surface profile shape memory is built in the structure of the micro-mechanical elements of the self-tilted micromirrors so that each micromirror plate has the required motion.
