Abstract

An optical distance measuring device and a method for operating an optical distance measuring device are disclosed. In an embodiment an optical distance measuring device includes a pixelated radiation source with at least two pixels, a radiation detector configured to detect electromagnetic radiation emitted by the radiation source and reflected in measuring regions and a control unit configured to operate the radiation source and to receive electrical signals from the radiation detector, wherein the pixelated radiation source is configured to illuminate different measuring regions with electromagnetic radiation with pairwise different properties.
