dc.description.abstract本篇論文主要在探討鈮酸鋰晶體角度多工全像儲存之理論及技術. 在理論 W, 我們計算光折變穩態光柵的繞射效率及記錄多重影像時其最佳化條件 , 包含參考光所需要改變的最小角度, 以及多工儲存之曝光時程等. 由計 漵珣o到的晶體與系統之參數則用來作為光學系統之設計之依據. 在實驗 上, 我們首先測量鈮酸鋰晶體全像光柵之最小角度間隔, 以與理論結果相 珊傢□ 其次我們建立一套角度多工的光學儲存系統, 並在一個2x2x0.7立 方公分大小的晶體的5個位置中, 分別儲存200張影像, 每個儲存位置的大 小約為0.25平方公分. In this thesis, we investigate the theory and experimental technique of an angular-multiplexing holographic storage system. A photoregractive crystal is used for the holographic medium. Inhe theoretical part, we calculate the diffraction efficiency ofsteady-state photorefractive grating. Then we find the optimumditions of the holographic storage system. These include theum angle separation between the angular multiplexingng and the exposure schedule for obtaining an uniform diffracrion efficiency in the multiple storage. In the experiment aspect, we first measure the minimum angle deviationetween the neighboring exposures. The experimental results areagreement with our calculation results. Then we have recordedimage holograms in five positions of a 2x2x0.7cm3 lithiumate crystal. The area of each position is 25mm2.zh_TW
