摘要： A micromirror array lens consists of many micromirrors with two degrees of freedom rotation and actuating components. As a reflective variable focal length lens, the array of micromirrors makes all lights scattered from one point of an object converge at one point of image plane. As operational methods for the lens, 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 semiconductor microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. Independent control of each micromirror is possible by known semiconductor microelectronics technologies. The micromirror array can form a lens with arbitrary shape and/or size, as desired.

摘要： A variable focal length lens comprising micromirrors with pure translation is invented. The lens consists of many micromirrors and actuating components. The array of micromirrors with pure translation makes all lights scattered from one point of an object have the same periodic phase and converge at one point of image plane by using Fresnel diffraction theory. 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 semiconductor microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. The lens can correct aberration by controlling each micromirror independently. Independent control of each micromirror is possible by known semiconductor microelectronics technologies. The micromirror array can also form arbitrary shape and/or size of a lens.

摘要： A Micromirror Array Lens comprises a plurality of micromirrors arranged on a flat or a curved surface to reflect incident light. Each micromirror in the Micromirror Array Lens is configured to have at least one motion. The Micromirror Array Lens forms at least one optical surface profile reproducing free surfaces by using the motions of the micromirrors. The free surface can be any two or three-dimensional continuous or discrete reflective surface. The Micromirror Array Lens having the corresponding optical surface profile provides optical focusing properties substantially identical to those of the free surface. The Micromirror Array Lens can forms various optical elements such as a variable focal length lens, a fixed focal length lens, an array of optical switches, a beam steerer, a zone plate, a shutter, an iris, a multiple focal length lens, other multi-function optical elements, and so on.

摘要： The present invention provides a fast optical shutter function by use of the fast movement of the micromirrors. In a micromirror array lens (MMAL), all the micromirrors reflect the incident light to form an image on the image plane. If the micromirrors reflect the incident light out of the optical sensor area, then the optical sensor can not have any optical signal just like the incident light blocked. By just changing the beam path by MMAL motion, the micromirror array lens has a function for optical shutter.

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.
摘要翻译：需要一种可以改变放大倍率的小型和快速光学变焦装置。传统的变焦装置需要耦合的机械运动来调节单个或多组元件之间的轴向分离，以便改变光学倍率。机械运动降低变焦速度，增加变焦系统的空间和重量，可能会引起不必要的抖动，并需要较大的功耗。此外，机械变焦系统仅限于放大轴上的区域。为了解决常规变焦系统的问题，发明了利用一个或多个可变焦距微镜阵列透镜而不具有透镜的宏观机械运动的变焦系统。
