Abstract
A device for determining the deviation of a target provided with a retrorector from a predetermined location in three spatial directions has a laser and a quadrant detector arranged next to it, which can be displaced jointly in the three spatial directions X, Y, Z. In this arrangement, the Z-setting is readjusted with the aid of a range measurement, so that the target is optimally illuminated. On the basis of the signal in the quadrant detector a displacement in the X-direction and Y-direction is effected in order to obtain a zero signal from the quadrant detector. The readjustments in the three directions are a measure of the deviation which can be displayed on a display via control electronics.
