Abstract:	近年由於頭戴式顯示器的可視範圍(Field of View，FOV)會受到系統上元件孔徑的限制，需在其光場上進行優化調製，然而，光場的放大需要一些特殊光學元件的加入而達到擴增效益，但可同時亦增加了頭戴式顯示器的重量。本研究中，我們提出使用體積全像光導元件來取代繁重的微透鏡系統，並將元件之波前紀錄於體積全像片中，以適應用於可視穿型式混合實境(Mixed Reality，MR)顯示技術領域。透過不同焦距的微透鏡系統的波前紀錄於全像片中，觀察在不同焦距下的角度放大變化量，並同時估算理論，最後與實驗進行比較與驗證。 ;Currently, the field of view (FOV) of head-mounted displays is qenerally limited by system constraints and requires magnification on the light field. However, optical components are needed for light field magnification, increasing the weight of the head-mounted display. In this study, we propose using volume holographic optical elements instead of the cumbersome microlens system, recording the wavefront on a volume holographic plate for use in mixed reality (MR). We recorded the wavefront information under different focal length of microlens systems on to holographic plates to observe changes in angle magnification at different focal lengths, estimating the theory and comparing and verifying with experiments.
