“…The compact lidar for ecology and meteorology has been used to monitor the dust, aerosols and other air pollutants and their distribution and movement in an industrial environment. The lower cloud boundary height can be determined in the range of 100 to 1000 m by means of the compact Lidar [28,29].…”

Solid state single photon detectors are receiving more and more attention in a number of areas of applied physics: optical sensors, communications, quantum cryptography, optical ranging and Lidar, time resolved spectroscopy, opaque media imaging and ballistic photon identification. This paper reports on results of research and development in the field of solid state single photon detectors at the Czech Technical University in Prague over the last 20 years. Avalanche photodiodes specifically designed for single photon counting devices have been developed based on various semiconductor materials: Si, Ge, GaP, GaAs and InGaAs. Electronic circuits for biasing, quenching and control of these detectors have been developed and optimized for different applications. The sensitivity of solid state photon counters spans from 0.1 nanometre X-rays up to 1800 nanometres in the near infrared region. Timing resolution of solid state photon counters as high as 50 picoseconds full width at a half maximum has been achieved when detecting single photon signals. Circuits permitting operation of solid state photon counters in both single and multiple photon signal regimes have been developed and applied. The compact and rugged design, radiation resistance, and low operating voltage are attractive features of solid state photon counters in various space projects.

“…Their utilisation in city monitoring systems is more promising in view of recent creation of the portable backscatter lidar with eye-safe energy level for environmental sensing. The lidar had been developed in the Space Research Institute of Russian Academy of Sciences by Pershin et al(1992) on the basis ofthe original Lidar-nephelometer for the Mars-98 Balloon and Rover mission. It is based on a single photon detection technique and operates at an extremely low energy level.…”

Instantaneous air pollution fields in towns have mosaic structure and to measure its probability function one needs a measuring network with great number of sensors. The problem can't be solved purely by means ofa computer simulations because ofthe turbulent character ofthe air flows among buildings. In present paper we studied this problem by using of lidar measurements and computer simulations simultaneously. The lidar data was used for the model parameterization. To simulate the atmosphere transport ofthe pollution puffs over city buildings we developed the special computer trajectory model. It takes into account the processes of plume widening while spreading over obstacles The model is easily adjusted on the base of a plume geometrical and transparensy lidar measurements. It uses the approximation of a quasipotential flow. The model accounts the widening of a plume flowing around buildings through effects of air volumes scattering on the potentials that represent building configurations. This method was used to study air polluted zones from one of Moscow heat power station.

The lidar device as part of the meteorological complex of the ExoMars-2022 landing platform is designed to study Martian aerosol, the planetary boundary layer, and small-scale atmospheric turbulence. A miniature lidar based on a pulsed semiconductor laser and an avalanche photodiode in the photon counting mode will make it possible to obtain aerosol backscattering profiles along a vertical path from 10 to 1500 m during the day and from 15 to 10 000 m at night. In the passive mode, the sky brightness is measured in a narrow spectral range and in a narrow solid angle with a frequency of up to hundreds of hertz. The measured fluctuations can provide information about the turbulence of the daytime atmosphere and its relation to dust activity. In the paper we considered the scientific tasks of the experiment, the program of measurements on the surface of Mars and described in detail the components of the equipment and the features of their work.
