Adjustable laser processing beam positioning system
The granted patent (Publication Number: US11982819B2) describes a system that includes a calibration laser beam source, a laser processing beam source, a laser scanner, a fiducial calibrator, a camera, at least one processor, and computer-readable storage media. The system is designed to adjust the positioning of the laser processing beam relative to transient optical fiducials produced by the fiducial calibrator. These adjustments are made based on images captured by the camera and processed by the processor, ensuring precise control over the laser processing beam.
Furthermore, the system incorporates various features such as multiple transient optical fiducials produced along non-common paths with the laser scanner's scan, dynamically positionable optical fiducials directed along separate optical paths, and the use of diffractive optical elements in the fiducial calibrator. The calibration process involves comparing the detected position of the fiducials to the laser processing beam's position, updating a scan error correction table, and controlling the laser scanner accordingly. Additionally, the system allows for adjusting the positioning by following the dynamically positionable optical fiducial according to a predetermined laser processing pattern, detecting it with the camera, and guiding the laser processing beam based on the detection. Overall, the system described in the patent aims to enhance the accuracy and efficiency of laser processing by utilizing optical fiducials and advanced calibration techniques.
