本研究以偏振干涉術配合SPR技術，再結合了CCD取像，整合出可以量測出一整面的折射率分佈的全場SPR相位儀。本解相系統的相位解析度為0.3度，整體系統對折射率的靈敏度為3*10^-6 RIU(Refractive Index Unit, RIU)。本論文之實驗為量測出細微折射率的改變，以及驗證系統基本功能。此相位儀在實驗上可以分辨出濃度差1%酒精溶液(折射率差約0.0004RIU)。本系統具有即時、高靈敏度、大量平行篩檢等優點。若能實際結合生醫微陣列晶片的設計，對於量測生物分子的反應、DNA檢測等，均有廣泛的應用。 A surface plasmon resonance (SPR) technique with full-field phase detection is proposed. In our full field system, we combine a method of the polarization interference for phase detection, SPR technique and CCD Video camera. The resolution of phase detection is about 0.3 degree, and the measurement sensitivity of refractive index is about 3*10^-6 RIU (Refractive Index Unit). There are several advantages like immediate detection, high sensitivity and parallel examining in our system .
