Photodetector Module for Recording Lidar Signals in the Near-Infrared Region

摘要

A basic platform for photodetector modules used in the lidar complex for recording backscattered radiation in the near-infrared region is described. High-voltage pulse noise of DC/DC converters in the photodetector modules are reviewed and tested. A method is proposed for compensating the noise generated by such converters. The tests carried out in the lidars of the Institute of Atmospheric Optics, SB RAS, showed the effectiveness of the module designed to record signals in analog mode at a wavelength of 1064 nm.
