本篇論文主要目的在於研究體積全像位移多工之位移靈敏度，吾人提出一新穎的90度紀錄架構，以訊號光為平面波，參考光為球面波，在參考光光路上置入導光管(Light pipe)，進行一系列實驗，並藉由相位疊加法(Volume hologram being an integrator of the lights emitted from elementary light source，簡稱VOHIL)理論的分析，與實驗結果做驗證。於此一研究中吾人發現，光折變晶體在接收同樣數值孔徑(Numerical aperture)的參考光下，可提高體積全像之縱向位移靈敏度。
此外，於實驗過程中，我們遇到電動平移台位移不精確、齒輪間隙所產生的實驗誤差，以及實驗歸一化的問題，因此我們亦同時針對這些問題設計一套實驗步驟與分析方法，以得到精確的測量數據。
相信此一研究對於探討光學儲存的儲存容量，以及利用全像晶體進行共焦顯微鏡解析度之提昇等研究，必能有所助益。

In this thesis, we study the longitudinal selectivity of volume holographic optical elements. We propose a 90-degree geometry with inserting a light pipe in the reference arm. According to the analysis by VOHIL model and experimental demonstration, we find that the light pipe is useful to enhance longitudinal selectivity of the volume holographic optical element. The enhancement of the longitudinal selectivity can be applied to enhance multiplexing capacity of volume holographic storage and to increase resolution of confocal microscope
based on volume holographic filter.
