在本文中，我們針對離軸式體積全像儲存系統架構推導其數學模型，並利用此數學模型計算系統在多工儲存多頁間的串音影響及位元誤碼率，並分析系統之容忍度。我們也提出「定點讀取系統」、「持續轉動讀取系統」兩套系統間的比較。最後我們進行實驗，並驗證位移補償系統與布拉格選擇性之正確性。

In the thesis, we study the off-axis volume holographic data storage system, and we simulate the bit error rate , multi-page intercross-talk effect and analyze the system tolerance. We propose to calculate the bit error rate with single-point readout algorithm and multiple-point readout
algorithm. Finally, we build up the experiment system to verify the displacement compensation and Bragg selectivity by the theoretical calculation.
