全像資訊儲存技術俱備超高儲存容量與及二維資訊存取技術，而被視為最具潛力的下世代儲存技術。本研究藉由相位疊加法以及純量繞射理論建立了同軸式全像資訊儲存系統之理論模型，以此理論模型推導出之近軸近似解，可幫助我們掌握系統的物理特性，我們藉此提出最佳解決方案。本文首先探討參考光分布對點光源擴散響應以及位移選擇性的影響。接著在參考光加入相位調製，有利於使用較低功率的雷射光源以及系統微型化，並且減少點擴散響應半寬。藉此增加單一頁面內位元資訊，進而同步提升系統儲存容量與讀寫速度。

The holographic data storage possesses ultra-high capacity and two-dimensional access technology. It is regarded as the most promising storage technology in the next generation. Based on VOHIL and scalar diffraction theory, we construct the theoretical model of the collinear holographic data storage system. According to the theoretical model, we derive the paraxial solution, which can help us to grasp the physical characteristics and propose the best solution. First, we discuss the effects of the distribution of the reference patterns on the point spread function and the shift selectivity in this paper. Then, we add the phase modulation in the reference pattern. It facilitates the lower power of the laser light source and miniaturization of the system. What’s more, it decreases the half width of the point spread function. By adding more bits within per page, we enhance the capacity and accessing speed synchronously.
