Optoelectronic sensor and method for detecting transparent objects

An optoelectronic sensor, for detecting transparent objects in a monitored zone, the optoelectronic sensor having:

• a light transmitter for transmitting a light signal,
• a light receiver for generating a received signal from the received light signal,
• an evaluation unit that is configured to evaluate the received signal and to generate an object determination signal that indicates whether a transparent object has been detected in the monitored zone, and
• an output for outputting the object determination signal,
• wherein the evaluation unit is further configured to recognize with respect to the received signal and to a piece of reference information whether a detected transparent object has an additional feature and to output a corresponding piece of additional feature information,
• and wherein the evaluation unit is configured to use a piece of information acquired from an integrated received signal of a reference object as the piece of reference information, with the reference object being a transparent object to be detected with and/or without an additional feature.
