摘要： A two-dimensional image projection device using array of micromirror array lenses and a random scanning technique is invented. Using the random scanning technique, the light efficiency is nearly doubled than that of the prior art. The invention makes a brighter and less power consuming display device possible. Because each micromirror array lens of array of micromirror array lenses can scan whole image plane, a fast self diagnosis and correction technique can be introduced in displaying device. The Self diagnosis and correction technique makes display device to maintain image quality even a few tens percent of micromirrors do not work properly. Owing to the scanning characteristics of micromirror array lens, the image projection device can express the same number of pixels image with less number of micromirrors than the prior art. This also enables small sized two-dimensional image projector, which can be incorporated in portable electronic equipments.

摘要： A discretely controlled micromirror array lens (DCMAL) consists of many discretely controlled micromirrors (DCMs) and actuating components. The actuating components control the positions of DCMs electrostatically. The optical efficiency of the DCMAL is increased by locating a mechanical structure upholding DCMs and the actuating components under DCMs to increase an effective reflective area. The known microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. The lens can correct aberrations by controlling DCMs independently. Independent control of each DCM is possible by known microelectronics technologies. The DCM array can also form a lens with arbitrary shape and/or size, or a lens array comprising the lenses with arbitrary shape and/or size.

摘要： 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.
