Abstract
In a process for generating a stereoscopic video picture by using partial images for the left eye and the right eye of an observer, which partial images emit light with different polarization states oriented orthogonally relative to one another, wherein the observer perceives the stereoscopic video picture through spectacles with eyepieces which filter the respective polarization state of the light. At least one light source is used for generating every partial image. This light source emits a substantially parallel, polarized light bundle which can be controlled with respect to intensity and whose polarization state is identical to one of the two orthogonal polarization states or can be converted into this polarization state with low loss and is raster-scanned on a screen to generate at least one partial image. A corresponding device comprises at least one light source which emits a polarized, substantially parallel light bundle which is controllable with respect to intensity and at least one raster scanning device for the left-to-right, top-to-bottom, line-by-line deflection of the light bundle on a screen for displaying at least one of the two partial images.
