本論文旨提出利用體積全像光元件結合波導技術來製作光導的方法，以實現光場技術。光場是透過透鏡陣列使影像資訊在每一個區域都有著不同的光資訊，最終帶有三維資訊的影像，可以解決目前頭戴式顯示器的視覺輻輳調節衝突之問題。在光導的製作，體積全像光學元件具有角度選擇性之特性，以取代透鏡陣列上的每一個子透鏡，萃取出影像的不同視角，並設計全像透鏡使視角放大，解決市售近眼顯示器視角的不足。實驗中，製作橫向與縱向的子透鏡陣列，並以相位疊加法模擬，在滿足布拉格條件各子透鏡所萃取的視角。實驗結果表示出以體積全像光學元件製作子透鏡，可萃取到不同的子畫面，子畫面視角可相差2.79度，且子畫面的視角放大2.2~2.3倍間。;This is proposes a method for creating optical waveguides using volume holographic optical elements combined with waveguide technology to realize light field technology. The light field, through an array of lenses, ensures that each region contains different optical information, ultimately producing images with three-dimensional information. This can solve the current visual convergence-accommodation conflict issue in head-mounted displays. In the creation of optical waveguides, volume holographic optical elements, with their angle selectivity characteristics, replace each sub-lens in the lens array, extracting different perspectives of the image. Additionally, holographic lenses are designed to magnify the viewing angles, addressing the insufficient viewing angles in commercial near-eye displays. During the experiments, lateral and longitudinal sub-lens arrays were created, and simulations were conducted using phase superposition to meet the Bragg conditions for the viewing angles extracted by each sub-lens. The experimental results demonstrated that sub-lenses made with volume holographic optical elements can extract different sub-images, with a viewing angle difference of 2.79 degrees between sub-images, and the viewing angles of sub-images are magnified by a factor of 2.2 to 2.3.
