“…We use a glass cover plate with a slant edge as shown in Figure 13 for the easily matched incident angle. ö=9O-tan1O=5.3 (3) cos4: =flg cos(+ô) Refractive index is 1.515 and we chose the ratio ten for k. Thus the angle is calculated 73.5° degrees as follows.…”

A display system requiring no special glasses is a useful technology for three-dimensional(3-D) images. The lenticular display system has such defects that it has a non-planar screen and views a blur. In this paper, a newly developed, 3-D real-time display with a HOE is described.This simple 3-D display can improve above-mentioned problems. And the advantage of the screen HOE is that the number of presented views is much greater that of an equivalent lenticular display, because the screen HOE can multiplex pixels both horizontally and vertically to display lateral views. This screen HOE can be made more easily and smoothly.The trial screen HOE is 4"x5" and consists of 128,000 holograms. Therefore, the image size measures approximately 4"x5", and the resolution is 200x160 pixels x 4 views.
