The Tunnel Profile Projection System is designed for displaying a preset tunnel profile on a plane. Utilizing a computer to generate the trajecting vectors of a Laser beam reflecting system from the predefined tunnel profile. The reflecting controller set the angular displacement and speed for both vertical and horizontal angular positioning system to reflect the Laser beam.The trajectory of reflected Laser beam constructs a predetermined tunnel shape on a vertical plane from the Projection system. The Projected tunnel profile will help the operators effectively during the tunneling operation.
