Abstract
The invention relates to an optoelectronic device ( ) for detecting markings affixed to objects by using a transmitter ( ) that emits light rays ( ), a receiver ( ) that receives light rays ( ), an evaluation unit ( ) and a deflection unit ( ) at which the transmitting light rays ( ) are reflected and, as a result, are periodically guided inside a predetermined angular range. At least two stationary reflecting units are installed in series after the deflection unit ( ). The transmitting light rays ( ) are guided over the first reflecting unit inside a first segment &Dgr;&agr; of the angular range &Dgr;&agr;, so that these rays periodically scan a first segment of a three-dimensional detection range. Inside of a second segment &Dgr;&agr; of the angular range &Dgr;&agr;, the transmitting light rays ( ) are guided over a second reflecting unit, so that these rays periodically scan a second segment of the three-dimensional monitoring range. The object can be introduced into the detection range for detecting the markings on the object.
