Abstract : The patent describes a beam scanning technique for a high power laser beam. This is accomplished by sequentially deflecting successive thin layers of the beam in such a way that each thin strip of deflected laser light passes across a narrow aperture mask. The laser light passing through the aperture is effectively a scan of that layer of the laser beam. It is subsequently focused onto an appropriate laser beam detector. A spiral arrangement of radial reflector rods mounted on a rotatable drum support structure is used to achieve sequential deflection of successive layers of the laser beam.
