Optoelectronic sensor unit and method for operating an optoelectronic sensor unit

摘要

The present invention relates to an optoelectronic sensor unit with at least a transmission unit to the emission of detected light into a detection range and at least one receiving unit for the detection of reflected from the detection range detection light reflected or. According to the invention, at least in the cylinder, a wide variable optical element in the beam path of the detection beam between the at least one transmitter unit and the detection range or in the beam path of the from the detection area of the at least one receiving unit provided detection light reflected or remitted. The present invention also relates to a method for operating an optoelectronic sensor unit.
