Abstract
A method for verifying the functionality of a laser scanner includes 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 so 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 this detection, at least two detector signals are generated. A pulse width is ascertained for each of the detector signals by a computing unit, and a ratio of the pulse width of a first detector signal to the pulse width of a second detector signal is ascertained. The operability of the transmitter unit and/or the detector unit is verified on the basis of said ratio.
