Abstract
The availability of higher resolution display panels has increasingly made glasses-free 3D displays become a viable mainstream commercial product; it is therefore important to define and measure their parameters. We will discuss the measurement of multiview 3D displays that use a slanted lenticular screen in front of the display panel to control the light directions. Multiple perspective views are formed across the viewing field giving viewers the sensation of depth and motion parallax. In addition to the usual parameters of resolution, luminance, contrast etc., it is important that we know the image depth of field (DOF). In this paper, we will first define the DOF and then describe means of measuring it. The aim of the paper is to describe general theory and procedure, and not the measurement of specific displays. However, a comparison of the results on a sample test display of the three methods described, is reported in order to give an indication of accuracy.
