Abstract
Mie scattering lidar is widely used in the field of atmospheric detection. Photomultiplier Tube (PMT) module is usually used to collect echo signals. Whether the PMT module can reliably receive and convert backscatter echo signals directly determines the accuracy of lidar inversion data. Conventional plus high-voltage power supply for gain adjustment, there are problems such as inconvenient operation and low adjustment accuracy. In this paper, a gain control system of PMT module based on FPGA is designed for Mie scattering lidar. The host computer sends a specified command to the FPGA according to the communication protocol, and the FPGA driver DAC controls the adjustment of the gain of the PMT module. The experimental results in the Mie scattering lidar system show that the detection system has the advantages of convenience, rapidity, high precision, practicality and reliability.
