Abstract

A method of autostereoscopic imaging including providing an autostereoscopic illumination unit including a lens field composed of a multiplicity of individual lenses or concave mirrors, and modulating an emission characteristic of the light source such that the individual lenses or the concave mirrors are illuminated only partly by the light source, wherein light from the light source impinges on the individual lenses or concave mirrors such that an emission characteristic of a three-dimensional object is imitated, the lens field extends over a spatial angle range of at least 2 sr relative to the light source or an external observer, the individual lenses or concave mirrors are distributed over the lens field and are at least partially sequentially irradiated, and the light source is formed by one or more lasers and the laser or each of the lasers irradiates/irradiate only one of the individual lenses at a specific point in time.
