Beschreibung
Zusammenfassung:	An exemplary system generally includes an additive manufacturing machine, an optics assembly, a first sensor, a second sensor of a different configuration from the first sensor, and a controller. The additive manufacturing machine is configured to selectively scan a build beam across a region of interest to thereby add material to a workpiece at a moving build point located in the region of interest. The optics assembly is configured to separate electromagnetic radiation emitted from the region of interest into a first beam and a second beam. The first sensor is configured to receive the first beam and to generate first information related to the first beam. The second sensor is configured to receive the second beam and to generate second information related to the second beam. The controller is configured to calibrate the second sensor based upon the first information and the second information.
