Paper Abstract

We discuss implementation of the combined node scanning SRS lidar system for high-speed and high spatial resolution (about 3 cm) scanning in wide and narrow angle at a distance of 50-100 m. Narrowband scanning is performed by the deflector moving along a spiral path. Rotating angle wedges of the deflector deviate a beam by an angle of ± 50. This design constitutes an "optical reduction" wedge between the steering angle and the deflection angle of the optical axis and allows 15 ' positioning accuracy. overview of the entire study area for no more than 1 ms at a frequency of rotation of each of the wedges of 50-200 Hz. Unambiguous definition of the geographical coordinates of the probed object is achieved by using high-precision GPS-module and the Vincenty's algorithms. It allows to build a 3D spatial distribution of concentrations of air pollutants.
