Abstract
The profile of a surface of an object is determined by scanning the line of intersection of this surface and a given plane transverse to the object. A radiation transmitter provides a transmitting beam, and a radiation receiver provides a receiving beam. Deflection means causes scanning movement of one or both of the beams so that a zone of intersection of the beams scans along a predetermined line and a detector in the receiver receives radiation transmitted from a source in the transmitter and reflected by the surface of the object. The deviation of the actual line of intersection from the predetermined line is determined from data supplied by the detector at a plurality of positions along the line of intersection.
