Analysis of color distortions in a transmission-type holographic screen.
Full-color transmission-type holographic screens for displaying stereoscopic and multiview images suffer color distortions, especially at their edges. These distortions arise because the reconstructed image of the diffuser appears not at a specified location at different locations for different parts of the screen. Analysis shows that the diffuser strip, which is an object that records the screen, should be extended further in the photoplate direction than in the conventional position to remove the distortions and that use of a short-wavelength laser in the blue spectral region, along with extending the diffuser, is recommended for recording large-sized screens. The analysis also allows the largest sizes of screens that can be recorded for a given set of parameters to be calculated. A comparison of the quality of the images displayed on the screens recorded in the conventional position and in the newly developed position has shown distinctive improvements for the new position.
