A laser scanner mounted to ships and submarine vehicles is providing high-resolution images of underwater features, including shipwrecks. The ULS-500 PRO scanner from 2G Robotics uses a high-sensitivity, low-noise sensor to reach ranges previously unattainable with laser scanning, resolving fine-scale dimensional features from distances as far as 20 meters. The system was used offshore during

The pioneering Aladin sensor, a spaceborne LiDAR instrument with two powerful lasers, a large telescope and very sensitive receivers, is ready to join its Aeolus satellite for launch in 2017. Designed by Airbus Defence and Space, Aladin’s laser generates ultraviolet light beamed toward Earth, which bounces off air molecules and small particles such as dust,

NASA scientists and engineers are field testing the CO2 Sounder LiDAR, an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements from space. The instrument is a strong contender for a potential next-generation carbon-monitoring mission, the Active Sensing of CO2 Emissions over Nights, Days and Seasons (ASCENDS). The LiDAR operates by

The three instruments on the Sentinel-3A satellite are now offering a tantalising glimpse of what’s in store for Europe’s Copernicus environmental monitoring effort. The latest images, which feature Europe and Antarctica, come from the sensor that records Earth’s radiant energy. Launched just three weeks ago, Sentinel-3A carries a suite of cutting-edge instruments to provide systematic
