Abstract

The present invention provides a Micromirror Array Lens (MMAL) with fixed focal length to reproduce a designed surface having optical focusing power. The micro mechanical structures with surface profile shape memory are fabricated and released after fabrication. Each micromirror in the MMAL has its own motion by stiction force and/or electrostatic force while and/or after the releasing process. Once the designed surface is formed, the MMAL has an optical power as a lens.
