Abstract:	本論文提出一個作為複雜波前體積全像光學元件的強繞射計算模型，企圖以結合相位疊加法與耦合波理論的特性來解決複雜體積全像之絕對繞射效率計算之問題。我們以孫慶成教授所提的相位疊加法的相位不匹配因子來對應耦合波理論的耦合強度因子，再結合上述二種理論模型來計算繞射光在空間上的分布。在模擬與實驗中，我們針對相位匹配和相位不匹配兩種情況進行強繞射現象的分析，並討論不同耦合強度對於繞射光在空間中分布的變化與布拉格選擇性的影響。;In this thesis, we proposed a strong diffraction model for a volume holographic optical element with complex wavefront. We try to make a connection between the phase mismatch factor of the VOHIL model by Prof. Sun and the coupling strength factor of couple mode theory. Based on these two models, we calculation the diffraction distribution from the complex volume hologram. In the simulation and the corresponding experiment, we analyze the diffraction of strong volume hologram with phase match and phase mismatch. Finally, we study the variation of the diffraction distribution and Bragg selectivity with different coupling strengths.
