Abstract: An arrangement for the display of images with selectable three-dimensionally visible or two-dimensional modes, including an illuminating device a filter array to impart a structure to the light a diffusing layer, and a transmissive image display device, with a variable distance a between the filter array and the diffusing layer, so that in a first position, the structure imparted by the filter array is essentially cancelled due to the light diffusion effect of the diffusing layer, and a two-dimensional image is shown, and the structure imparted by the filter array is essentially not cancelled, so that the image display device shows a three-dimensional image.

Abstract: The invention relates to arrangements for spatial display, and in particular to such arrangements that, by means of wavelength or gray level filter arrays, present an image visible in three dimensions to one or several observers without the use of auxiliary aids such as glasses. In such arrangements, an increased brightness of the 3D display is achieved by means of the arrangement of transparent filters on the filter array according to the invention.

Abstract: The invention relates to a simulation method, especially to a method for simulating spatial impressions which are produced by means of an image generator and one or several filter arrays. The method according to the invention essentially comprises the following steps: a) Specification of the geometry of the image generator, b) specification of the geometry of the filter array, c) specification of a spatial arrangement geometry in relation to the image generator and the filter array in a three-dimensional coordinate system (X,Y,Z), d) specification of two monocular positions of observation in front of the said arrangement geometry, e) specification of a combined image containing bits of partial information from several views Ak (k=1 . . .

Abstract: The invention relates to an autostereoscopic projection arrangement, comprising at least one projector (4) and at least one filter array (F1, F2), which has a multitude of filter elements arranged in columns and rows, in which arrangement bits of partial information from views of a scene or object are projected by the projector/the projectors (4) onto a projection screen (3), where these bits of partial information are rendered on image rendering elements and, having passed one or several of the filter arrays (F1, F2), are made visible to at least one observer (5), and in which, as regards the propagation direction of the bits of partial information, the image rendering elements correspond with correlated filter elements in such a way that an observer (5) will see predominantly bits of partial information from a first selection of views with one eye and predominantly bits of partial information from a second selection of views with the other eye, and thus will have a spatial impression.

Abstract: The invention relates to arrangements for spatially displaying a scene or object, in which a great number of individual pixels ?ij in a grid of rows (j) and columns (i) are made visible simultaneously, with the pixels (?ij) presenting bits of partial information from several views Ak (k=1 . . . n) of the scene or object, and in which propagation directions for the light radiated by the pixels (?ij) are established by means of a structured plate. The structured plate contains a great number of optical imaging elements (?pq) arranged in a grid of rows (q) and columns (p). According to the invention, at least two of the following kinds of optical imaging elements (?pq) are simultaneously provided on the structured plate, viz. wavelength or gray level filter, lens or cylinder lens, and/or prism.

Abstract: The invention relates to arrangements and methods for spatially displaying images of a scene or object, in which several viewers can get a spatial impression without the use of aids. Arrangements according to the invention comprise an image display device and at least one filter array with a great number of filter elements; characteristically, it is not in all rows (j) and columns (i) that partial image information from different views is alternatingly displayed by the pixels of the image display device in such a way that, from at least two monocular viewing positions, exclusively or almost exclusively partial image information from a single view is visible to one of the viewer's eyes, and that, from a great number of viewing positions, essentially bits of partial image information from different views are visible monocularly to both eyes of the viewer, and that the viewer has a spatial view of the scene or object displayed.
