Abstract
A device for accurately positioning laser scribed lines in a thin top layer of material with respect to lines already scribed in lower layers for the purpose of making solar panels. An alignment detector system is attached to and displaced from an optics unit that generates laser beams by a distance such that the detector measures the position of scribed lines in the lower layers in the area of the panel that will be scribed at a subsequent time. A motion and control system moves the panel such that the detector follows the path of one or more of the lines scribed in one of the lower layers and measures the position of the lines. The system accepts data from the alignment detector and uses the data to correct the relative position of the optics unit.
