A smart LIDAR based on compact Nd:YAG laser for atmospheric fine particulate matter

Abstract

A Smart LIDAR system based on an innovative Nd:YAG laser designed for operation at three wavelengths (1064 nm, 532 nm and 355 nm) is presented. The repetition rate of the emitting module of up to 4 kHz allows for the basic version of the described system to achieve a spatial resolution of 187.5 cm. The system is a smart mobile device/unit ideally suited for: (i) studies of time-vertical variation of atmospheric fine particulate matter, (ii) 3D reconstruction of plumes from stationary and mobile sources, e.g., emitted by industrial stacks of industrial plants, ships, airplanes, vehicles, etc. Preliminary results with the proposed systems operating at 532 nm and 355 nm are reported here.
