Abstract
A laser-materials processing system including means for determining an incident diameter of a laser beam at a point of laser beam-material interaction on a workpiece, is disclosed. A filtered image of the interaction point is transmitted, via an imaging fiber bundle, to a video camera. The analog video signal generated thereby is digitized and provided to a computer which evaluates the pixel magnitudes along a beam image diameter line to determine therefrom the incident laser beam diameter.
