Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
137 words
A device for measuring deviation from a predetermined location in three spatial directions of a target provided with a retroreflector, the device comprising a laser, a position-sensitive detector adjacent the laser, a common element within which the laser and detector are arranged, optical imaging devices for directing a beam from the laser onto the retroreflector and for imaging reflected light onto the position-sensitive detector, and a laser range measuring device, the common element being arranged for common linear displacement in said three spatial directions, the common element having a power source and control means for tracking the common element in a laser beam direction to a position which corresponds to a measured range as determined by the laser range measuring device and in directions perpendicular thereto a position for which the position-sensitive detector transmits a zero signal.
Claim 2
Independent Claim
137 words
A device for measuring deviation from a predetermined location in three spatial directions of a target provided with a retroreflector, the device comprising a laser, a position-sensitive detector adjacent the laser, a common element within which the laser and detector are arranged, optical imaging devices for directing a beam from the laser onto the retroreflector and for imaging reflected light onto the position-sensitive detector, and a laser range measuring device, the common element being arranged for common linear displacement in said three spatial directions, the common element having a power source and control means for tracking the common element in a laser beam direction to a position which corresponds to a measured range as determined by the laser range measuring device and in directions perpendicular thereto a position for which the position-sensitive detector transmits a zero signal.
