Paper Abstract

The full color transmission type holographic screen for 3D image projection has a vertical direction viewing zone size of 6.5 cm. This size is too small for viewers to watch images with comfort. To increase the vertical size of the viewing zone, a vertical diffuser with an optimized scattering angle and a diffraction grating with vertical dispersion are recorded and used together with the screen. With attaching the diffuser or the grating to the screen, the vertical size of the viewing zone is increased up to 5 times with little degrading in image quality. Recording the grating and the screen on a single photo plate by exposing once is also possible. The screen performance is examined with a holographic screen with size of 60 by 80 cm2.
