Abstract
A system for analyzing laser beam characteristics at field of view extremities in high-speed laser motion systems, wherein the high-speed laser motion systems comprise a laser that generates a non-stationary laser beam and a build platform positioned at a predetermined location relative to the non-stationary laser beam, comprising a known or pre-defined field of view of the laser, wherein the laser beam characteristics are known or determined at a center location of the field of view; and a plurality of pin-hole sensors mounted at the field of view extremities, wherein each pin-hole sensor measures the laser beam characteristics at the field of view extremities, and wherein differences between the laser beam characteristics at the center location and the laser beam characteristics at the field of view extremities are captured and accounted for in the high-speed laser motion system during processing.
