An autostereoscopic display includes a background illumination with a multiplicity of parallel light strip groups with in each case at least two parallel light strips, wherein the individual light strip groups are arranged next to one another with a first grid dimension, and a lens grid arranged before the background illumination and has a multiplicity of parallel lens strips, wherein the lens strips are arranged next to one another with a second grid dimension, as well as a light modulator arranged before the lens grid and displays image information.

Autostereoscopic display that provides a 3-dimensional visual impression

A projection apparatus for scanningly projecting an image onto an image field by means of a radiation beam includes a modulator for modulating an intensity of the radiation beam such that the intensity of the radiation beam changes in a time interval during which a scan point to which the radiation beam is directed sweeps a pixel of the image field.

Projection apparatus for scanningly projection

A scanner for providing a possibility of detecting a surface relief of an object includes a projector configured to guide a light beam in an illumination line over the surface relief to obtain an illuminated location on the surface relief, the projector being further configured to output a projection signal from which a position of the light beam in the illumination line is derivable. Additionally, the scanner includes a collector having a collector micro mirror stimulatable to oscillate in two dimensions and a point-shaped light detector, the collector micro mirror being oscillatingly arranged in a first direction of the illumination line and in a second direction differing from the first direction such that a reflection of the illuminated location within a scan area of the micro scanner mirror is imagable by it onto the point-shaped light detector, and the collector being configured to output a detection signal from which a position of the illuminated location in the first and second directions is derivable.
