Abstract

A method for measuring distances and for determining the three- dimensional contour of a workpiece, which includes directing two intersect- ing light beams (3,4) onto a workpiece (12) to be measured, determining the light points (13,14) produced by the beams on the workpiece surface and measuring the angles ( alpha , beta ) of inclination of the striking beams in their common plane. The laser light beams (3,4) may be scanned along a contour (12) by means of pivotting coupled mirrors (5,6) and the light spots (13,14) position determined by photodiode screens (17,18), the beams being of different colours to be separated by a dichroic mirror (16), or one beam may be scanned much faster than the other and the inclination valves ( alpha , beta ) taken when the two spots coincide. <IMAGE>
