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： 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： A micromirror array lens includes a micromirror lying in a micromirror layer, an electrode configured to displace the micromirror by electrostatic force, and a control wire coupled to the electrode and configured to supply voltage to the electrode to generate electrostatic force. In one embodiment, the control wire lies in a gap between the micromirror and another micromirror in the micromirror layer. In another embodiment, the control wires lie beneath the micromirror layer, such that the fill-factor of the micromirror array lens is optimized. In another embodiment, the micromirror array lens includes a passivation layer configured to provide electrical isolation between the electrode and the control wire. The advantages of the present invention include improved optical efficiency and accuracy by minimizing the voltage variation of electrode and control wire by each other and electrostatic force between control wire and micromirror.

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 variable focal length lens comprising micromirrors with one degree of freedom rotation is invented. The lens consists of many micromirrors and actuating components. The array of micromirrors with one degree of freedom rotation makes all lights scattered from one point of an object converge at one point of image plane by using rotation of micromirror. The micromirror has the same function as a mirror. Therefore, the reflective surface of the micromirror is made of metal, metal compound, multi-layered dielectric material, or other materials with high reflectivity. The actuating components control the rotational displacements 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 CMOS technologies can remove the loss in effective reflective area due to electrode pads and wires.

摘要： A variable focal length lens consists of many micromirrors with degrees of freedom rotation and/or degrees of freedom translation and actuating components. As operating methods for the lens, the actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The optical efficiency of the variable focal length lens is increased by locating a mechanical structure upholding micromirrors and the actuating components under micromirrors. The lens can correct aberration by controlling each micromirror independently. The lens can also be of a desired arbitrary shape and/or size. The micromirrors are arranged in a flat plane or in a curved plane with a predetermined curvature. The electrodes determining the position of the micromirrors can be made of material with high electrical conductivity, preferably metal. The surface material of the micromirror is made of a material with high reflectivity such as aluminum, silver, and gold, which are coated with multi-layer dielectric material or antioxidant.
