| dc.description.abstract | 目前市面上主流之智慧型手機，厚度多在1公分之下，而隨著越來越薄的體積限制，其相機鏡頭的製作難度也不斷提升。因此，如何能在更小的空間中，賦予成像裝置更多的功能，也成為各家手機業者不斷研究的課題之ㄧ。在本論文中，我們提出了一種結合微機電元件與反射式光學架構而成的薄型光學變焦系統，其特點在於藉由可形變面鏡的曲率改變，以達到影像的真實放大與縮小、且因為採用了全反射式的架構，在沒有透鏡的存在下，同時消除了可觀的色像差。總體來說，因其制動系統的低功率消耗，與多重摺疊的光學路徑，使得這種成像系統有實現在未來手機製作上的潛力。 | zh_TW |
| dc.description.abstract | The thickness of the smart phones in today’s market is usually below than 10 mm, and with the shrinking of the phone volume, the difficulty of its production of the camera lens has been increasing. Therefore, how to give the imaging device more functionality in the smaller space is one of the interesting research topics for today’s mobile phone companies. In this paper, we proposed a thin optical zoom system which is combined of micro-electromechanical components and reflective optical architecture. By the adopting of the MEMS deformable mirrors, we can change their radius of curvature to reach the optical zoom in and zoom out. Furthermore, because we used the all-reflective architecture, so the system has eliminated the considerable chromatic aberrations in the absence of lenses.
Generally speaking, due to the adopting of low power consumption actuated system (MEMS deformable mirror) and the multi-folded light path, we believed this system has the potential to be applied in the mobile phone camera in the future. | en |
