Abstract

Geometric overlapping coefficient is one of the key factors for the near distance signal processing in lidar detection field. Based on the geometric analysis of Mie-polarization lidar, three kinds of shape of the overlapping area of between the telescope field of view and the laser of an off-axis Mie-polarization lidar in close range was discussed and studied. The overlapping nalytical formula for the off-axis lidar overlapping coefficieints was preseneted. Finally, based on the analytical formula and the Gauss distribution of the laser beam, the varying curve of the overlapping coefficieint of the multi-wavelength polarization scattering Lidar was obtained and discussed. According to the experiment results, the geometrical overlapping coefficient distribution along with distance is relative stable under condition of proper operation. But after long distance transportation or adjustment of lidar architecture, the geometrical overlapping coefficient should be obtained through field experiment.
