    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 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: 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: 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: This invention provides a Hybrid Micromirror Array Lens with reduced chromatic aberration over a broadband wavelength range of light. Conventional micromirror array lens uses phase matching condition. Therefore, the optical surface profile of Micromirror Array Lens using the same phase condition has a discontinuous surface profile. As the required optical power of Micromirror Array Lens is increased, the number of profile discontinuity of Micromirror Array Lens is increased. Therefore, the chromatic aberration is increased. To minimize the chromatic aberration, the number of profile discontinuity should be minimized. The number of discontinuity is reduced when the optical surface profile has a simulating base curve, called a translation contour with optical power. Hybrid Micromirror Array Lens is invented to reduce a large translational amount and chromatic aberration for large optical power lens.
