Abstract
A method and device for three-dimensionally depicting images, in which a sequence of two-dimensional individual images are produced by means of a two-dimensional array, which consists of individually controllable light-emitting diodes (LED's) and which focuses light emitted by the LED's of the array onto a projection device. The light striking the projection device is focused onto a diffusing screen. While coupled to one another, the projection device and the diffusing screen are moved in a periodically reversing manner in a direction that is essentially perpendicular to the screen plane, and the sequence of two-dimensional individual images are synchronized with the spatial position of the diffusing screen.
