Spot-separable temperature measurement arrangement, used in laser manufacturing process, has optical detector with optical filter for measuring electromagnetic radiation caused by irradiated laser on operating area formed on workpiece

摘要

The arrangement irradiates laser beam (1) to a specific operating area (5) provided on a workpiece (4). An optical detector (2) with an optical filter (3) measures the electromagnetic radiation caused by the laser on the operating area formed on the workpiece. The optical detector may be a charge-coupled device (CCD) camera, CCD array camera or CMOS array camera. An independent claim is included for the spot-separable temperature measurement method.
