Improvement of fill factor in pinhole-type integral imaging display using retroreflector
Posted on 2017-12-20 - 18:14
A retroreflector array improves the visual quality of three-dimensional (3D) image of the pinhole-type integral imaging display. Conventionally, the limited size of apertures of the pinhole array restricts the fill factor of the pixelated 3D images. We propose the system with a retroreflector, which consists of the array of corner cubes, which increases the fill factor of the pixel by the diffraction. The pixel spreading model is developed by an equivalent corner cube structure. The simulation of pixel spreading by Fraunhofer diffraction agrees well with experimental results, and proves the effectiveness of the proposed method to improve the visual quality while not sacrificing the viewing angle and the depth perception.
