摘要： A testing apparatus adapted to be placed within a laser powder bed fusion additive manufacturing device. The portable testing apparatus includes a support having an upper surf ace that is positioned parallel to and above the build plane, and that is adapted to receive and absorb laser light generated by the non-stationary laser beam; a plurality of pin-hole defining structures mounted at predetermined locations in the support such that each pin-hole defined is positioned to receive the laser light generated by the non- stationary laser beam, and such that each pin-hole is elevated at a predetermined height above the upper surface of the support and parallel thereto; a fiber optic cable disposed within each pin-hole defining structure, wherein the cable has a proximal end at which the laser light is received through the pin-hole and a photodetector located at the distal end of each fiber optic cable that converts the laser light delivered to the photodetector into electrical voltage output signals.

摘要： A system for removing a coating from a surface is provided. This system includes a laser scanner, wherein the laser scanner further includes at least one laser source, wherein the at least one laser source is operative to generate at least one laser beam, and wherein the laser beam is directed onto a work surface by the laser scanner; and a controller for operating the laser scanner. The controller further includes an imaging device for imaging the work surface; a lighting device for illuminating the work surface and overwhelming light generated by the interaction of the laser beam with the work surface; and a processor for processing information collected by the imaging device and adjusting the power output of the at least one laser source, if and when desirable or necessary.
