Compact polarization lidar system at a 1550  nm wavelength for aerosol anomaly detection

The study of atmospheric aerosols, which are defined as fine particles suspended in the atmosphere, using lidar techniques is well established. This work presents real-time measurements of aerosol hotspots, particularly water mist, sand, and Arizona test dust, using a portable polarization lidar system. The system, which consists mainly of commercial off-the-shelf components, has a spatial resolution of approximately 3 m, weighs less than 10 kg, and operates at a wavelength of 1550 nm. Due to its wavelength, the lidar has high potential for eye safety.
