Zusammenfassung:	Aspects described herein relate to additive manufacturing systems and related methods. In some embodiments, an additive manufacturing system includes a laser array position detector to determine a position and/or orientation of laser energy pixels in a laser array. The laser array position detector may include an aperture and an optical sensor positioned within the aperture to detect laser energy from a laser energy pixel when the laser array is scanned across the aperture.
