Paper Abstract

Precise guidance of high energy laser beams is important in industrial laser machining to optimize the use of the available power and to assure high quality work. A crossed beam depth gauge has been designed that measures the distance to the workpiece surface with an accuracy of one part in two thousand over a range of 10 cm. The television camera based system is described along with an analysis of its performance.
