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.
