| dc.description.abstract | 當前市面所發表之頭戴式顯示器，主要遇到投影系統在使用者視角上的限制問題，同時需兼顧外觀及微型化的設計。因此，本文使用體積全像光學元件之光導設計來製作MR眼鏡，以達到頭戴式顯示器的輕量設計。
本論文主要的目的是分析使用具有擴瞳功能之一維光導系統時，所遇到的縱向可視角限制成因，並藉此替代二維擴瞳之縱向可視角放大。本文使用體積全像光學元件來製作一維光導，透過光導系統中各參數與出瞳成像的關係，來分析橫向及縱向可視角的影響成因，其中包括出瞳大小、波導厚度、光資訊在波導內之繞射角度、guiding distance等參數，透過實驗進行比較與驗證。 | zh_TW |
| dc.description.abstract | Current commercially available head-mounted displays (HMDs) primarily face the limitation of projection systems in the user′s field of view (FOV) while also requiring a lightweight and compact design. Therefore, this paper employs a waveguide design based on volume holographic optical elements (VHOE) to fabricate MR glasses, achieving a lightweight design for head-mounted displays.
The main purpose of this paper is to analyze the causes of the vertical field of view (FOV) limitations encountered when using a one-dimensional light guide with exit pupil expansion, and to use this to replace the vertical field of view enlargement of two-dimensional exit pupil expansion. In this paper, a volume holographic optical element (VHOE) is used to fabricate a one-dimensional light guide. The relationship between the parameters in the light guide system and the exit pupil imaging is used to analyze the influencing factors of the horizontal and vertical FOV, including exit pupil size, waveguide thickness, diffraction angle of optical information in the waveguide, and guiding distance. The results are compared and verified by experiments. | en_US |
