Lidar with SiPM: Some capabilities and limitations in real environment

The purpose of the work is to demonstrate real capabilities and to give examples of SiPMs application in lidar technology in both analog and photon counting modes. The experimental research within an operating lidar complex adapted to implement the analog mode and photon counting measurements with subsequent inversions of atmospheric extinction and backscattering coefficients was conducted. Theoretical evaluations of potential limitations of atmospheric lidar by use of real day-time background parameters and features of SiPM-photodetectors studied experimentally were carried out with comparison of the extent of sensitivity decreasing for different detectors used and estimations of their operation range reduction.

► We demonstrate real capabilities to use SiPMs as lidar detectors in both analog and photon counting modes. ► We model SiPMs and PMTs as lidar detectors capable to work under intense day-time skylight. ► We examined limitations of SiPMs caused by intense background radiation.
