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.

An apparatus for optically exploring the surface of a body, comprising: a source of light selectively trainable upon the surface to be explored for distinctively illuminating a generally punctiform area thereof; optical means for intercepting reflected light rays from said punctiform areas, passing along two divergent paths, and for respectively focusing said light rays into a pair of image points projected upon at least one receiving surface; and evaluating means responsive to said optical means for converting the locations of each of said image points with respect to at least one reference point into an indication of the position of said punctiform area relative to said receiving surface.
