Abstract
The invention relates to arrangements for spatially displaying a scene or object, in which a great number of individual pixels αij in a grid of rows (j) and columns (i) are made visible simultaneously, with the pixels (αij) 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 (αij) are established by means of a structured plate. The structured plate contains a great number of optical imaging elements (βpq) 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 (βpq) are simultaneously provided on the structured plate, viz. wavelength or gray level filter, lens or cylinder lens, and/or prism.
