Abstract:
1. A projection system comprising: at least one image projection apparatus, at least one transparent screen deflecting the light from the image projection apparatus into a plurality of discrete, mutually spaced directions so that a free area which is free from images is formed between identical images, and a plurality of projected, mutually spaced holographic frames of at least one image visualized by the transparent screen, wherein the transparent screen comprises at least one film layer which is partially illuminated multiple times at different pick-up angles to a same object of an image, so that the film layer has a plurality of hologram images of the same object at mutually different pick-up angles, wherein the transparent screen looks transparent to a viewer in the free area at angular ranges between adjacent frames, and wherein light intensity at the adjacent frames is a factor of 2 to 10 higher than the light intensity at the free area.
