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： 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： A virtual keyboard input system using three-dimensional motion detecting by variable focal length MMAL is provided. The compactness of the virtual keyboard input system is accomplished by the variable focal length MMAL performing three-dimensional imaging function. Since the three-dimensional imaging process occurs in a very short time scale, the system can determine the motion of the input by the user and track the motion of the user in real-time based response. Image processor can determine which input is occurred at the moment and the time-dependent profile of the motion itself. The input system gives an output just like a conventional keyboard and a mouse system.

摘要： A pocket-sized two-dimensional image projection device adapted to a portable device is invented. The pocket-sized two-dimensional image projection device projects two-dimensional image on a projection surface with arbitrary profile and arbitrary distance from the projection device, and arbitrary attitude about the projection device. The position, profile, and attitude of the projection surface about the projection device can be arbitrary because the projection surface is not embodied in the projection device to reduce size of the device. Each micromirror array lens has the ability of scanning and focusing on the projection surface. The focusing on the projection surface can be achieved by automatic focusing function of micromirror array lens. Therefore, an in-focused two-dimensional image can be displayed on arbitrary projection surface. Also, this invention makes a brighter and less power consuming display device, which give an advantage for the portable device application.
