Title
(EN) Variable focal length lens and lens array comprising discretely controlled micromirrors
(ZH) 变焦透镜及包括离散受控微镜的透镜阵列
Abstract
(EN) A discretely controlled micromirror array lens (DCMAL) consists of many discretely controlled micromirrors (DCMs) and actuating components. The actuating components control the positions of DCMs electrostatically. The optical efficiency of the DCMAL is increased by locating a mechanical structure upholding DCMs and the actuating components under DCMs to increase an effective reflective area. The known microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. The lens can correct aberrations by controlling DCMs independently. Independent control of each DCM is possible by known microelectronics technologies. The DCM array can also form a lens with arbitrary shape and/or size, or a lens array comprising the lenses with arbitrary shape and/or size.

本发明公开了一种离散受控微镜阵列透镜(DCMAL),其由许多离散受控微镜(DCM)及致动零件组成。该致动零件以静电方式控制DCM的位置。可通过在DCM下设置支持DCM及致动零件的机构以增加有效反射区域而增加该DCMAL的光学效率。已知微电子技术可消除因电极片及线路所造成的有效反射区域中的损失。该透镜可通过独立控制DCM而校正像差。通过已知微电子技术可进行每个DCM的独立控制。该DCM阵列还可形成具有任意形状和/或尺寸的透镜,或形成包括具有任意形状和/或尺寸的透镜的透镜阵列。
