Abstract
Generally, the autostereoscopic 3D displays provide the viewer with a truly 3D image without the need of any special glasses. In this paper, a new multiview autostereoscopic 3D display system using a photopolymer-based VHOE is proposed. The proposed system utilizes a time-multiplexed scheme where a series of views of a scene are displayed sequentially on a high-speed SLM and the VHOE acting as an optical directional modulator is synchronized with the image repetition rate to project each image to a spatially different zone in front of the screen. The VHOE is made by recording angularly different multiple interference patterns in the photopolymer hologram, and it can used to diffract the incident light to the spatially different positions by simply controlling the angles of the reference beam. In this paper, Dupont photopolymer is used for implementing the VHOE device and its physical properties such as sensitivity, diffraction efficiency for the optimal recording of diffraction gratings are measured. From some experimental results on the optical characteristics of the Dupont photopolymer-based VHOE, a possibility of implementation of the time-sequential multiview 3D display system using the VHOE is also suggested.
