Development of multifunction micro-pulse lidar at 1.5 micrometer

Taking advantage of the 1.5 mu m lidar, a series of 1.5 mu m micro-pulse lidars have been developed at the University of Science and Technology of China, in Hefei, China. According to the different characteristics of three kinds of single-photon detectors at 1.5 mu m, namely superconducting nanowire single-photon detector, up-conversion SPDs and InGaAs/InP single-photon avalanche diodes, different kinds of lidar systems have been constructed to realize the detection of atmospheric visibility, cloud, depolarization, wind field at the atmospheric boundary layer.
