Abstract:	本研究藉由模擬及檢測分析來製作出液晶偏振旋轉器(Tandem-2?-TNLC)，此液晶偏振旋轉器理想上能使入射光的偏振角度旋轉到期待的偏振角度上並且偏振態維持不變。接著以兩組偏振旋轉器(Tandem-90?-TNLC及Tandem-45?-TNLC)外加一片線性偏振片製作出偏振相機所需之電控偏振光學系統，以手機之聲源訊號驅動並切換液晶偏振旋轉器的四種偏振操作狀態，並以手機上的相機透過此電控偏振光學系統，依序紀錄四張偏振照片，進而以四張偏振照片計算得到偏振影像之偏振角度與偏振度資訊。;In this study, a liquid crystal polarization rotator (Tandem-2?-TNLC) was produced by simulation and detection analysis, this liquid crystal polarization rotator can rotate the polarization angle of the incident light to the desired polarization angle and maintain the polarization state unchanged. Then two sets of polarization rotators (Tandem-90?-TNLC and Tandem-45?-TNLC) plus a linear polarizer are used to make the electronically controlled polarization optical system required by the polarization camera, which is drive and switch the four polarization operating states of the liquid crystal polarization rotator with the sound source signal of the mobile phone, and use the camera on the mobile phone to record the four polarization photos in sequence through the electronically controlled polarization optical system, Furthermore, four polarization photos are used to calculate the polarization angle and polarization degree information of the polarization image.
