    Abstract: 在本論文中,我們以純量繞射光學與相位疊加法為基礎,分析體積全像之繞射訊號,並針對離軸式體積全像儲存系統之架構做了改良,且推導其數學模型,可提高徑向位移靈敏度,進而提升儲存容量。改良之架構加入參考光相位調制,並對亂相分佈及正交分佈之相位調制做出比較。In the thesis, we analyze diffraction image of volume hologram based on scalar diffraction theory and VOHIL theory. We improve off-axis volume holographic data storage system, and derive mathematical model. The Radial Bragg Selectivity is enhanced, and the capacity of disc increases substantially. We compare random phase distribution with orthogonal phase distribution in improved system.
