Light field Mirage using multiple flat-panel light field displays

This study proposes a digital implementation of the conventional Mirage, which uses two parabolic mirrors to produce 360-degree three-dimensional (3D) images of real objects placed inside of it. The two mirrors are replaced with multiple light field displays to generate rays emitted from 3D objects in 360 degrees. We propose two techniques for eliminating repeated 3D images produced by the multiple displays, that is, non-tracking and tracking techniques. The former supports multiple viewers, although the 3D image size is limited. The latter can produce large 3D images, although the number of viewers is limited. The display system of the lower half of the light field Mirage was constructed by using four light field displays to verify the proposed techniques.
