  7. Bergmans Mechatronics LLC Effect of Detector Movement on Beam Power Based on results of full-scale testing in coal-fired power plant duct: • For manually aligned system with 1.2” of detector movement, spot size must be 3.4” diam (9.1 in 2 area) • Auto-aligned system, spot size can be 1” diam (0.8 in 2 area) • Resulting power density of manually aligned system is 8.6% of auto-aligned system Detector 1.2” Launch 1” Ø 3.4” Ø 28 feet
