IMAGE TILING TECHNIQUE BASED ON ELECTRICALLY SWITCHABLE HOLOGRAMS

摘要

A projection system (26, 66, 74) and a method displaying a high resolution composite image on a projection screen (32) include a number of reconfigurable holographic optical elements (HOEs) (50, 52, and 54) in the projection optics (30, 76) of the system. The reconfigurable HOEs of the projection optics allow the system to direct multiple image segments of the composite image that are projected from a single image source toward different regions (42, 44, 46 and 48) of the projection screen to form the composite image on the screen. The reconfigurable HOEs of the projection optics operate to selectively diffract the image segments projected from an image generator to different regions of the projection screen when enabled to a diffractive state. The image segments that are diffracted by the projection optics produce the composite image on the projection screen.
