Anordnung zur Vermessung der Koordinaten eines an einem Objekt angebrachten Retroreflektors

摘要

A device is disclosed for measuring the co-ordinates of at least one retroreflector applied on an object. The light emitted by a lighting unit reaches the at least one retroreflector through a beam splitter, the light reflected from the retroreflector towards the beam splitter is separated from the path of the lighting beam, and said light falls on a detector unit by means of which the position of incidence of the detected light spot can be determined. The light from the lighting unit forms a beam which lights on the surface of the object a larger surface area than the surface area of the at least one retroreflector applied thereon. The detector unit is located in a place where the position and/or shape of the detected light spot change with the position of the retroreflector.
