Abstract
According to a method for verifying the functionality of a laser scanner () comprising a housing () with a light-permeable window (), a transmission unit () inside the housing (), a deflection unit (), and a detector unit () inside the housing (), at least one test signal () is transmitted by the transmission unit () during a test phase. The deflection unit () is oriented in such a way that the at least one test signal () is not directed to the window (). Components of the at least one test signal are detected by the detector unit, and based on said detection, at least two detector signals are generated. A computing unit ascertains a pulse width for each of the detector signals and calculates a sum of the pulse widths. The operability of the transmission unit and/or the detector unit is verified on the basis of said sum.
