Beam quality and intensity are critical characters of high energy laser system.Accurately measuring the far-field laser beam spatial profile is an effective way to diagnose laser beam quality and study the atmospheric transmission effects for a high energy laser system.In this paper,a detector array system for mid-infrared laser beam profile measuring is developed.The system is consisted of optic attenuators,photoconductive HgCdTe detectors,amplifiers,analog to digital converter unit,wireless transmission u...
