摘要

本文目的在設計一輸出為兩束線性偏振折射光裝置，並分析其輸出分離角及偏振態特性。這個裝置由Rochon稜鏡及半波長旋轉器所組成。兩束線性偏振折射光的特色具相同波長、相位及線性偏振態，此特性將使其廣泛被應用於生物光電檢測、光學檢測儀器、照明及投影系統…等。利用ZEMAX光學設計程式多重組態進行這兩束線性偏振折射光分離角及偏振態設計與分析。一般傳統雙折射偏振稜鏡製作是雙折射偏振稜鏡加工完成之進行量測，本文創新方法是先量測模擬再進行雙折射偏振稜鏡加工。本裝置設計結果光學口徑20mm、使用波長0.4μm、分離角2.37°及雙線性輸出偏振光。

The purpose of this paper is to design a polarized device of two linear polarized refracted beams and analyze its output splitting angle and polarization state. This device splits the incident beam into two linear polarized outgoing light beams and consists of a Rochon prism and a half wave rotator. These two linear polarized outgoing light beams have the same wavelength, the same phase and the same linear polarization state. The two linear polarized outgoing light beams are established by multi-configuration mode from ZEMAX optical design software to analyze the output splitting angle and the polarization state. This polarized device is useful for a light source of E-O testing system and a liquid crystal projector. The design results of polarized device are the out splitting angle of two linear polarized outgoing light beams with 2.37° and the p-polarization outgoing light beam. In general, the manufacturing process of the polarization prism is to measure the performance of the polarization prism after making it. In this paper we initiate a new method in the reverse way. That is, using the simulation, after the performance of the polarized prism reaches to the specification, and then we make it. So, it can lower the cost of the product and also decrease the time of research and development.
