    Abstract: 本論文主要是設計出一款薄型化光學指紋成像系統,分析其成像的相關特性,包含成像放大率和探討要如何擺放架構中的光源,使系統內的光接收器有最大範圍的響應。本論文發展出可用於反射式指紋辨識系統之設計,搭配空間多工和時間多工的方法,使我們可取得大量的指紋資訊。另一方面,如何提升成像對比度 (Visibility) 亦為本論文之研究,先就物理特性去探討,找尋可利用於系統之材料,為具特殊性質之光學薄膜,使影像明視度增加,進而研發出一款辨識度高且可應用於手持式裝置內的薄型化光學指紋成像系統。;In this thesis, we design an optical fingerprint imaging system in slim structures and analyzed optical performances of Imaging. The analysis includes the Imaging magnification and the location of the light source, and it can improve the dynamic range in system. In the thesis, we have successfully design, which can be applied to reflective fingerprint identification system with temporal multiplexing or spatial multiplexing, and to get more fingerprint information.
    On the other hand, the importance of image visibility cannot be overestimated. With the help of experimental analysis and optimized in simulation, the optical film with special physical properties can enhance the visibility of imaging has been approved. Finally, we design of optical fingerprint imaging system in slim structures with better imaging visibility which can be applied to handheld device.
