ABSTRACT:
An array of micromirror array lenses is invented. The micromirror array lens consists of many micromirrors and actuating components. Each micromirror array lens is variable focal length lens with high speed focal length change. The lens can have arbitrary type and/or size as desired and desired arbitrary optical axis and can correct aberration by controlling each micromirror independently. Independent control of each micromirror is possible by known microelectronics technologies. The actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The optical efficiency of the micromirror array lens is increased by locating a mechanical structure upholding micromirrors and the actuating components under micromirrors. The known microelectronics technologies remove the loss in effective reflective area due to electrode pads and wires.
