Abstract
A method is described for determining angle errors when measuring slewing angles of a pivoted light-deflecting device, including the following steps: emitting a first light beam and a second light beam, which enclose a light beam angle, onto the light-deflecting device; receiving the first light beam and second light beam deflected by the light-deflecting device and reflected by an object; calculating a first propagation path of the first light beam and a second propagation path of the second light beam; pivoting the light-deflecting device from an initial position to a final position, respective slewing angles of the light-deflecting device being measured in the process and a dependency of the first propagation path on the measured slewing angles being determined; and calculating an angle error for a measured slewing angle to be corrected from the set of measured slewing angles by using the light beam angle, the second propagation path and the dependency of the first propagation path on the measured slewing angle.
