  • Laser work station with optical sensor for calibration of guidance system
    Patent number: 5304773
    Abstract: A laser work station has a base member, a laser head mounted on a laser head support carried on the base member for movement of the laser head relative to the base member, so that it is movable thereon in X, Y and Z axes. A guidance system effects precision movement of the laser head in the X, Y and Z axes to move the beam about a workpiece, and an optical sensor assembly comprising a light source and light sensors about the light source to detect light reflected from the surface of the workpiece. The sensor assembly is operable to detect reference formulations on the workpiece as it is moved thereabout.
