Hydrogen Sulfide Molecules Lidar Sensing in the Atmosphere
摘要： The optimum operation modes of the Raman lidar and the differential absorption and scattering lidar for the hydrogen sulfide molecules sensing in the atmosphere at the low permissible concentration level have been studied and the error estimation of the hydrogen sulfide molecules concentration measurement in the atmosphere by the Raman lidar and the differential absorption and scattering lidar has been executed. The computer simulation of the two types of such a lidar equations has been fulfilled for this purpose. The measurement relative accuracy for the range of the studied molecules concentration of 1011–1014 cm–3 at the 3.83 μ laser radiation wavelength and the ranging distances from 10 do1000 m lies in the range of 20–26% for the differential absorption and scattering lidar.

摘要： The development of radioelectronics and informative–and–communicative technologies of the XXI century is associated with the transmission of ever increasing volume of data and is oriented to use of subTHz and THz bands – SHF, EHF, and HHF (0.1 – 10 THz). Elements and devices of these bands can be conditionally divided into 2 levels: up to 1THz electronic equipments are effectively uses, over 1 THz –are photonic devices. The development of photonic technologies is of increasing importance both in the telecommunicative and in the space communication systems. In this report the physical phenomena and processes occurring in magnetooptical (magnetophotonic) composite material media capable of optimally ensuring their efficiency have been investigated to create new element baseline for domestic radioelectronics. The creation of new–generation functional devices capable of operating in subTHz and THz frequency bands will entail the rapid development of telecommunications.
