Abstract
A device is described for detecting the position of an object, which device comprises a radiation source, beam-splitting prism, and a detection system comprising a plurality of radiation-sensitive detectors. The object to whose position is to be measured carries only the prism, and each detector is divided into a plurality of subdetectors. The device enables changes in both position and inclination of the object to be measured.
