Abstract
Design characteristics of a turbulent lidar, which affect its thermo-mechanical stability, are determined. Two different designs are compared with different approaches to the selection of transceiving optics and detectors and arrangement of the temperature control system for stabilizing the lidar optical bench. A procedure is suggested for simulation of the lidar transceiver, including the calculation of the displacements of optical elements relative to the base points on the optical bench and the ray tracing from the laser into the atmosphere and back. The effect of the temperature gradient between the opposite sides of the optical bench on the operation of the receiving channels is analyzed. The results of the experimental study of lidar resistance to temperature changes are described. Recommendations for improving the design of a turbulent lidar are formulated.
