发明名称 Projection device for simultaneously generating a plurality of mutually spaced, holographic frames of one and the same image by means of a holographic screen
摘要 A projection system includes an image projection apparatus window and a transparent holographic screen deflecting light from the image projection apparatus into discrete, mutually spaced directions so that an area which is free from images is formed between identical images. Projected, mutually spaced holographic frames of the image is visualized by the holographic screen that includes a film layer which is partially illuminated multiple times at different pick-up angles to the same object of an image, so that the film layer has hologram images of the same object at mutually different pick-up angles. The transparent screen may include many holographic film layers, in which each film layer is illuminated once at different pick-up angles to the same object, so that each film layer has one hologram image of the object at a different pick-up angle.
