Abstract

A 3D sensor for monitoring a monitored zone is provided, wherein the 3D sensor has at least one light receiver for generating a received signal from received light from the monitored zone and has a control and evaluation unit that is configured to detect objects in the monitored zone by evaluating the received signal and to determine the shortest distance of the detected objects from at least one reference volume, and to read at least one distance calculated in advance from the reference value from a memory for the determination of the respective shortest distance of a detected object.
