Airborne Lidar Sensors

摘要

The first commercial airborne Lidar systems appeared on the market in the mid-1990s. This active remote-sensing technology rapidly evolved to become the laser scanners which can today emit 400,000 pulses per second and record the full waveform of the backscattered signal. Soon they will be even able to record half a billion full waveforms per second. In tandem with the new product survey on airborne Lidar sensors (see our website), the author here gives an overview of status and developments, particularly focusing on beam divergence, multiple pulses in air and full waveform recording, and associated opportunities for existing and new applications.
