The ALS40 now offers multi-mode operation, 1-3 return intensity with automatic gain control (AGC), as well as 38 kHz pulse rate at 100 percent duty cycle flying at 2 km, and up to 50 kHz below 1.5 km. The new capabilities allow users to collect highly detailed LIDAR data, tailor the system's operations mid-flight, respond to higher variations in altitude and signal strength, and decrease data storage requirements and processing time.
