Abstract
The apparatus for providing an autostereoscopic view of three dimensional structures includes a display device including several different two-dimensional views of a three-dimensional structure, optical image forming devices arranged in front of the display device and a screen for forming images in an observation plane from light rays issuing from the optical image forming devices so that images of the two-dimensional views appear in respective observation zones in the observation plane. The optical image forming devices (AE) are provided with aperture stops and include a device for overlapping the observation zones (BZ6) to form overlapping zones (UZ6). The aperture stops are provided with edge regions having a continuous transitional decrease of light transmission from complete transmission at their edges to zero transmission at a predetermined distance from their edges.
