Paper Abstract

In this paper, optical characteristics of the photopolymer-based VHOE for a new time-multiplexed multiview autostereoscopic 3D display system is analyzed. The photopolymer-based VHOE is recently, proposed as a optical directional modulator for projecting the time-multiplexed multiview stereo images to the spatially different directions. Since the VHOE is made by multiplexed recording of the multiple directional gratings in a photopolymer material, the resolution and parallax number of the VHOE-based 3D display system can be limited by the photopolymer's physical and optical properties, in general. Accordingly, to make the photopolymer-based VHOE to be applicable for a multiview autostereoscopic 3D display system, it is required to have some important properties such as low distortion, uniform intensity & high diffraction efficiency of the diffracted light beams, etc. In this paper, the optical and physical characteristics of the Du-Pont photopolymer-based VHOE such as the degree of distortion & uniformity of the light beam diffracted from the VHOE, its photosensivity and diffraction efficiency are measured and discussed.
