  • Compact optical apparatus for tracking a path of movement of a tool along a line of travel on a workpiece
    Patent number: 4683493
    Abstract: A compact optical apparatus for tracking a path of movement of a tool along a line of travel on a workpiece, includes a light source for providing a collimated light beam, wherein the light source is mounted on the tool adjacent the rear of the tool. A cylindrical reflector is mounted adjacent one side of the tool and is positioned in the path of the collimated light beam to reflect at least a portion of the collimated light beam to project a light stripe on the workpiece in front of the tool. The cylindrical reflector is positioned with respect to the collimated light beam and the line of travel of the tool so that the projected light stripe is substantially bisected by the line of travel. A camera is oriented to face away from the workpiece and is used to generate an image of the light stripe projected on the workpiece.
