Abstract
Disclosed herein is a laser beam measurement system that includes a beam measurement device, a positioning apparatus, and a control system. The beam measurement device can include an imager and a plurality of optical elements configured to form an optical path to the imager within the beam measurement device. The positioning apparatus is configured to adjust a position of the beam measurement device relative to a build plate of a laser powder bed fusion system. The control system is configured to determine an intended measurement position to observe a laser beam profile of the laser powder bed fusion system, determine a target position of a beam measurement device to align with the intended measurement position, and command an adjustment of one or more aspects of the beam measurement device to achieve alignment of the target with the intended measurement position.
