Depth Reduction in Light-Field Head-Mounted Displays by Generating Intermediate Images as Virtual Images

摘要
Light-field head-mounted displays (HMDs) can resolve vergence-accommodation conflicts, which may cause visual discomfort and fatigue. However, light-field HMDs have a narrow field of view (FOV), owing to their small display size and optical configuration. We increased the FOV by adopting a large display and shifting the elemental image from the back of the corresponding microlens. In this study, we proposed a method to generate intermediate images as virtual images to reduce the distance between the microlens array and the eyepiece. We also designed a microlens array suitable for the proposed method and successfully reduced the device depth by 44%.
