Paper Abstract

Several types of auto-stereoscopic display systems have been developed. We also have developed a real-time color auto-stereoscopic display system using a reconstruction method of parallax rays. Our system consists of an optical element (such as lens array, a pinhole, a HOEs and so on), a spatial light modulator (SLM), and an image-processing unit. On our system, it is not probability to appear pseudoscopic image. The algorithm for solving this problem is processed in an image-processing unit. The resolution limitation of IP has studied by Hoshino, Burckhardt, and Okoshi. They designed the optimum width of the lens or the aperture. However, we cannot apply those theories to our system. Therefore, we consider not only the spatial frequency measured at the viewpoint but the performance of our system. In this paper, we describe an analysis of resolution for our system. The first we consider the spatial frequency along the depth and the horizontal direction respectively according to the geometrical optics and wave optics. The next we study the performance of our system. Especially, we esitmate the cross talk that the point sources from pixels on an SLM cause by considering to the geometrical optics and the wave optics.
