Abstract
Method for determining the position of a moving object in accordance with the triangulation process, whereby the point to be measured is located by two laser beams and the beams are reflected by a retro-reflector on the point to be measured and are detected via a lens and series-connected detectors. In order to measure the turning position of the object, the retro-reflector is partly silvered and the laser beams (t<-1 , t<-2 ), which pass through the retro-reflector, are detected by a sensor plane at some distance from the centre of the retro-reflector.
