Abstract: The invention relates to a concentrator arrangement for solar radiation which has a beam splitter for deflecting solar radiation by means of total reflection. Furthermore, the invention relates to a device for concentrating and converting solar energy which has such a concentrator and at least one device for the conversion of solar energy. Such devices for the conversion of solar energy are for example solar cells, solar modules or thermal solar collectors. The concentrators according to the invention are used for concentrating solar radiation just as in sun protection panels.

Abstract: A method for displaying image information on an autostereoscopic screen that is suitable for simultaneous display of a plurality of views visible respectively from at least one of a plurality of laterally offset viewing zones. A first stereoscopic half-image and a second stereoscopic half-image, which are perceptible simultaneously and together produce a stereoimage, are reproduced on the screen such that the first stereoscopic half-image is visible from two laterally offset and respectively continuous regions, while the second stereoscopic half-image is visible from a stereozone which is situated between the two mentioned regions and is smaller than each of these two regions.
