    摘要: A multi-step microactuator is provided with the multiple supports in a stepper plate to give multi-step displacement to a controlled object. The microactuator has advantages such that multiple motion can be applied to the controlled object and that the object can be controlled in a low driving voltage and that simple motion control is applied by digital controlling and that the degrees of freedom in motion of the object can be chosen by the number of the stepper plate and that only single voltage is needed for driving the micromirror motion. With many advantages, the multi-step microactuator provides a solution to overcome the difficulties in controlling multi-step motion.

    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.
