Abstract

A laser projector for chassis alignment has a laser light source emitting a laser light beam, an optical element which generates a structured laser light pattern when it is irradiated by the laser light beam, a detector which is situated in such a way that it is irradiated by a sub-area of the structured laser light pattern and generates an output signal which is correlated with the radiation, and an evaluation unit which compares the output signal generated by the detector with at least one predefined setpoint value and turns off the laser light source if it detects a significant deviation of the output signal from the setpoint value.
