Abstract
In order to determine the positions in space of certain points on the surface of a body, a laser beam is trained upon a selected punctiform area of that surface and two sets of reflected light rays, traveling along divergent paths, are intercepted and focused by one or two objectives upon one or two receiving surfaces to form a pair of image points thereon. The receiving surface or surfaces may be part of a television camera. The location of each image point with respect to a reference point is numerically coded for utilization in a calculator which mathematically determines the desired position.
