Abstract
A device for determining an angle between two workpiece surfaces, comprising a transmitter for producing a light beam, a continuously rotating directional rotor for emitting the produced light beam in a rotating emission direction perpendicular to an axis of rotation of the directional rotor, a receiver for receiving a reflected light beam when the emitted light beam is reflected antiparallel to the emission direction by one of the two workpiece surfaces, an emission angle sensor unit for determining emission angles of the emitted light beam at which the receiver receives the reflected light beam, a calibrating unit for determining at least calibration parameters, a memory unit for storing the calibration parameters and an error model, and an evaluation unit configured to determine the angle as a function of the determined emission angles of the light beam emitted by the directional rotor, the stored calibration parameters and the stored error model.
