Abstract

An optoelectronic sensor is provided for a repeated detection of objects at different object distances, having a light receiver for generating a received signal from received light, having an evaluation unit for generating object information from the received signal, and having a distance sensor for determining the object distance from a respective object. The evaluation unit is here configured to acquire a measurement variable from the received signal with respect to an object, to associate the measurement variable with the object distance measured for the object, and to form a first distribution of the measurement variable via the object distance after detecting a plurality of objects.
