Abstract
In this paper, we propose a new approach for viewing angle enhancement in a parallax barrier based one-dimensional (1D) integral imaging display system. The viewing angle in a parallax barrier integral imaging system is defined by the angle between the center of slit and exit ray from elemental image. In this regard, we employ a refractive index medium between the elemental image plane and parallax barrier. Thus, the use of a refractive index medium allows us to increase the angle of exit ray, and may result in a viewing angle enhancement of display system. To test the feasibility of the proposed method, experiments are carried out and the results are comparatively analyzed with the conventional method. Experimental results reveal that the proposed method outperforms the conventional method.
