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： Automatic focusing system is provided which comprises a mirror or a plurality of mirrors with a translation device. Automatic focusing can be made by the translation of mirror because focal plane can be changed by the translation of mirror. The translation device makes its motion by the electrostatic, electromagnetic and/or electrothermal forces. The mirror is controlled by the electrical signal from the image processor to get an in-focus image. Also the mirror can be controlled discretely. The image shift by translation is compensated by tilt of mirror and/or image processing.
