Title: Mobile multiwave lidar complexes

Abstract

Multiwave mobile lidar complexes (MLCs) are designed and developed. A number of vehicle-based MLCs are built. The set of complex lidar probing data obtained with the help of MLCs is synchronised in space and time, covers a large area (the operation range of an MLC is 15 km), and is based on a unified methodological approach. The results of probing contain information on the concentration and physical nature of atmospheric aerosol, chemical composition of the gaseous phase of the atmosphere, wind and turbulence. The obtained data form the basis for a complex analysis of the ecological situation and prognosis of its development. (laser applications and other topics in quantum electronics)

  • This paper reports on the anisotropy of medium in HBC area in Sichuan Province that was found in the processing and interpretation of P and SH wave data. Shear wave passing through anisotropic medium splits into two different waves; fast shear wave whose polarization direction is parallel to fracture trend in formations, and the slow shear wave that polarizes in the direction perpendicular to fracture trend. Fast and slow shear wave sections can be respectively obtained by using different layouts and data processing methods. The anisotropy coefficient can be derived from the travel times of fast and slow S-waves arrivingmore » at the same interface; it can also be obtained from the ratio of SH-wave velocity to converted wave velocity. Anisotropy coefficient reflects fracture density. Then the direction of fracture zone can be determined by making both X, Y- component detection in data acquisition and coordinate revolution in data processing. Without the above measures taken, we can roughly determine the direction of fracture zone in the light of structure-line trend.« less
  • This paper analyzes the interaction of a strong wave and one or two probe waves with an intrinsic semiconductor medium which is partially inverted by an injection current. The many-body interactions of the electron-hole excitations are described using recently developed generalized Bloch equations for semiconductors. Coupled-mode equations for the different light fields are derived and solved, and predict that the gain and the coupling coefficients experience asymmetric dips. These dips are generated by scattering of the strong field off carrier-density pulsations induced by the pump-probe interference.
