Abstract:
A method for orientation of the plane XY of an object to the focal plane Xâ€²Yâ€² of a laser scanner, which plane XY is to be optically scanned, comprising the steps of:first roughly orienting the object on an object holder; then, directing a laser beam successively in time to at least three different points P1, P2 . . . Pn lying in the plane XY and, in doing so, imaging each of the reflections proceeding from the points P1, P2 . . . Pn on a position-sensitive detector; determining an actual position value at the detector for each reflection and comparing said value with a stored reference position value; obtaining adjustment commands for changing inclination of the object holder from deviations of the actual position values from the reference position values; and changing the inclination of the object holder until points P1, P2 . . . Pn are located in the focal plane Xâ€²Yâ€².
