| dc.description.abstract | 本文提出一套用於擴增實境眼鏡（Augmented-Reality Glasses）之體積全像光學元件（Volume Holographic Optical Element, VHOE）擴瞳光導系統的角頻譜傳遞（Angular Spectrum Propagation, ASP）理論模型。該模型整合體積全像理論與角頻譜傳遞法，實現對VHOE的大角度繞射和光導內多次全反射的數值模擬。
研究中使用ＭATLAB撰寫程式碼，採用模組化設計，包含體積光學元件模組、正向頻譜傳遞法模組及斜向角頻譜傳遞法模組。以九個步驟建立完整的光傳遞流程：從輸入之耦合元件（VHOE1），經過光導內多次全反射，再到輸出之耦合元件（VHOE2），並分析VHOE厚度、讀取波長、VHOE頻域尺寸等關鍵參數。本論文之研究成果可作為高性能AR眼鏡設計與優化的參考依據。 | zh_TW |
| dc.description.abstract | This thesis proposes an Angular Spectrum Propagation theoretical model for an Exit Pupil Expansion lightguide system based on Volume Holographic Optical Elements for Augmented Reality glasses. The model integrates volume holographic theory with the angular spectrum propagation method to numerically simulate the wide-angle diffraction of VHOEs and the multiple total internal reflections within the lightguide.
The research uses MATLAB to write code, adopting a modular design that includes a volume optical element module, a forward spectrum propagation module, and a tilted angular spectrum propagation module. A complete light propagation process is established in nine steps: from the in-coupling element (VHOE1), through multiple total internal reflections within the lightguide, to the out-coupling element (VHOE2). Key parameters such as VHOE thickness, readout wavelength, and VHOE frequency domain size are analyzed. The research results of this thesis can serve as a reference for the design and optimization of high-performance AR glasses. | en_US |
