| dc.description.abstract | 在本論文中，我們以相位疊加法為基礎，建立同軸式體積全像儲存系統的模型並推導出系統繞射公式之近軸近似解。以此公式為基礎，分析各項參數對系統的影響，包含參考光分布、光源波長、透鏡焦距以及記錄介質厚度。接著在參考光部分加入相位調製，分析相位調製對系統的點光源擴散響應以及位移選擇性的影響。最後分析不同情況下系統的誤碼率以及訊雜比，作為光儲存系統效能的評估標準。 | zh_TW |
| dc.description.abstract | In this thesis, we establish the theoretical model of the collinear holographic storage system and derive the formula for readout lights under paraxial condition based on VOHIL model. According to the formula, we analyze the key properties of the holographic system, including the effects caused by the reference beam, by the wavelength, by the focal length of the lens, and by the thickness of the recording medium. Besides, we analyze the point spread function and the shifting selectivity when the reference light is phase modulated. Finally we simulate the BER and the SNR of the systems. | en_US |
