我們以相位疊加法為基礎，建立出一個同軸式體積全像儲存系統的理論模型，並且已求得其在真實空間中的近軸近似解。根據理論計算，證實本模型確實可掌握其具有微小的位移容忍度以及參考光分布對於繞射光分布的影響。此外，其他各項參數對系統特性之影響，包括參考光圖形的對稱性、紀錄介質之厚度、訊號光位置差異及加入相位調制的改良等皆進行探討。最後我們分析不同狀況下之系統的誤碼率及訊雜比，以做為光儲存效能之評估。

In this thesis, we build up a new theoretical model for the collinear holographic storage system based on VOHIL model. Besides, we obtain a formula under the paraxial condition to describe diffraction behavior of the system. According to our simulation, we can figure out the detailed diffraction properties of the system, including large shift selectivity and the effect on the diffraction pattern by the reference pattern. In addition, the diffraction characteristics are studied with several important parameters, including the spatial symmetry of the reference pattern, the thickness of the recording medium, the position-dependence of the signal and phase modulation. Finally, we analyze the performance of the storage system by calculating the bit error rate and signal-to-noise ratio.
