A micromirror array lens includes a plurality of micromirrors, and reproduces a predetermined free surface by controlling rotation and/or translation of the micromirrors. The micromirror is controlled by control circuitry, upheld by a mechanical structure, and includes a reflective surface. The predetermined free surface of the lens is changed by controlling rotation and/or translation of the micromirrors. The micromirrors are arranged in one or more concentric circles to form the lens. The micromirror has a fan shape, a hexagonal shape, a rectangular shape, a square shape, or a triangle shape. The reflective surface of the micromirror is substantially flat. The control circuitry is constructed under the micromirrors by using semiconductor microelectronics technologies. The micromirrors are actuated by electrostatic and/or electromagnetic force. The reflective surface of the micromirror is made of materials with high reflectivity. The lens is used for an imaging apparatus, video monitoring camera, a camcorder, etc.
A micromirror array lens comprising a plurality of micromirrors, wherein the micromirror array lens reproduces a predetermined free surface by controlling two degrees of freedom rotation and one degree of freedom translation of the micromirrors.
The lens 60, wherein the camcorder has functions comprising optical zoom, automatic focusing, three-dimensional imaging, and digital zoom.
