Engineer Matthew Linkswiler measures the laser power of the Airborne Topographic Mapper (ATM) in the forward cargo hold of the DC-8. The instrument pulses laser light in circular scans on the ground, which reflect back to the aircraft and are converted into elevation maps of the ice surface. Credit: Jane Peterson, NSERC
