摘要： An automatic focusing system comprises at least one micromirror array lens, an image sensor, and a signal processor. The micromirror array lens images an object and focuses the image on the image sensor. The image sensor receives the light and converts the photo energy of the light to electrical energy in the form of an electrical signal. The image sensor sends the electrical signal, which carries image data concerning the object, to the signal processor. The signal processor receives the electrical signal, compares the image quality of the image data to its focus criteria, and generates a control signal, which it sends to the micromirror array lens to adjust the focal length of the micromirror array lens. This iterative process is continued until the quality of the image data meets the focus criteria, and the process is completed within the afterimage speed of the human eye.

摘要： There is a need for a small and fast optical zoom device that can change magnification. Conventional zoom devices require coupled mechanical motions to adjust the axial separations between individual or groups of elements in order to change the optical magnification. The mechanical motions decrease the speed of zooming, increase space and weight for zoom system, may induce unwanted jitter, and require large power consumption. In addition, the mechanical zoom system is restricted to magnifying the area on-axis. To solve problems of conventional zoom system, the zoom system utilizing one or more variable focal length micromirror array lenses without macroscopic mechanical motion of lenses is invented.

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.

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 three-dimensional display device includes a two-dimensional display displaying a first image, and a variable focusing lens receiving light from the two-dimensional display and forming a second image. The variable focusing lens reflects light from the two-dimensional display. The first image includes a predetermined number of first depthwise images that are displayed within a unit time, and the second image includes corresponding second depthwise images. Each depthwise image represents the portion of the first image having the same image depth, and the two-dimensional display displays one depthwise image at a time. The focal length of the variable focusing lens changes according to the depth of the depthwise image being displayed. A micromirror array lens is used as the variable focusing lens. The micromirror array lens has enough speed and focusing depth range for realistic three-dimensional display.

摘要： The present invention provides an optical micromirror device and its array device and method for making the same. By introducing a sub coating layer and an over coating layer with a high reflective metal layer, the reflective layer of the micromirrors is protected from environmental circumstances, oxidation, degradation, acid, base, and galvanic corrosion of the micro-mechanical structures. Also the new coating structure enhances the performance of the micromirror array device by reducing degradation of the reflectivity of the metal layer, by providing anti-reflection in the optically non-effective area, and by protecting the micro-mechanical structures.
