Measuring Environmental Conditions Using LIDAR
Air, land and sea: What satellite imagery can’t do, LIDAR can.
Technologies help us measure, monitor, and understand our changing environment. While satellites are helping to image our planet, there are gaps. Remote sensing technologies, deployed on airborne, land-based, and undersea platforms, can provide range measurements that when combined with position data offer accurate, 3D coordinates and elevations that are helping to enable new science in environmental characterization.
Measuring air pollution
Countries around the world, particularly China, are investing in pollution control to detect, monitor, and inform differing levels of air quality. Recently, the COVID-19 pandemic forced stay-at-home orders, resulting in significant reductions in air pollutants - from both vehicle emissions and industrial plants - across urban and residential areas. As the country recovers, air quality gains reverse.
Airborne or land-based lidar can be used to generate a 3D image of the atmosphere, mapping levels of smog and other conditions. This technology can be used to monitor pollutants coming from stationary sources such as coal power plants, mobile sources, fires and motor vehicles. Lidar helps monitor the distribution of particles, dust, and other pollutants around the source.
Ocean exploration and conservation
Bathymetric lidar technologies must operate within 1-10kHz, requiring a unique combination of energy levels and pulsewidths. To maximize the resolution of the images, Quantum Composers designed the Spectrolite 10kHz blue laser – a non-standard line for Nd:YAG pulsed lasers - which was used to reduce interference from scattered light.
