Title: Device for relief image adapting, for the formation of three-dimensional images totally interactive with a physical video image issuing from the same source
Inventor: DESBORNES GERARD ROCH
IPC: G02B30/31
Filed: 2001-06-15
Abstract: The device produces two three-dimensional images belonging to two distinct planes in space.  The device has a grooved Fresnel lens (1) with two types of alternating etched zones: the first type I (3) with flat surfaces, and the second type II (4) having inclined surfaces; the grooved lens (1) is placed on a liquid-crystal optical modulator (8) which generates transparent (12) and opaque (13) zones facing the grooved zones of the lens; another liquid-crystal optical modulator (9) is placed on the side of the source (6) which generates the basic image. The opaque zones of the modulator (8) mask in alternation the zones of the first type then of the second type, and simultaneously the transparent zones of the same modulator are superimposed in alternation onto the sources of the second type then the first type; the spatial and temporal distribution of the transparent and opaque zones of each of the two modulators (8,9) allows a temporal and periodic selection of the preferred directions of visualization for generating two three-dimensional images.  In the second embodiment, the device has two grooved Fresnel lenses in mutually symmetric positions, and a liquid-crystal optical modulator placed between the two lenses; another grooved Fresnel lens placed on the side of the source is used to enlarge the source image and to increase the visual angle. In the third embodiment, another liquid-crystal modulator is placed on the side of the source and synchronized with the first modulator by an electronic clock (11). The device comprises a network of etched micro-lens zones and flat non-etched zones, which are distributed in strips or in a draught board fashion. The etched micro-lens zones are of parabolic type, and the non-etched zones are reflecting. The zones of the first type are inclined, and the zones of the second type are flat, reflecting, transparent, opaque or inclined. A particular spatial and temporal distribution of the zones of the two types is synchronized with a given video sequence and generates a relief on the basis of a unique video image of an object in a lateral phase, a lateral and vertical plane, or a horizontal plane, with a large viewing angle. The source image video sequence is constituted of an alternation of an image of the original sequence and complementary images of the same sequence, and the liquid-crystal modulator is transparent when source displays the original image, and it is opaque when the source displays the complementary image; when the modulator is transparent the light rays from the source image are reflected from the Fresnel lens to form a suspended image.
