Object detection system having an image detection system

Abstract

An object detection system has an image detection system with an imaging detector, a position detection system with a position detector, and optics which guide incident radiation onto both detectors. The two detectors are arranged one behind the other, in particular adjacent to one another, in the beam path. This makes it possible to achieve a simple, compact and reliable object detection system.
