An investigaton of laser radiation extinction in pyrotechnic aerodispersive clouds at 1.06 μm and 10.6 μm wavelengths

摘要

In the paper an extinction of the laser radiation at 1.06 and 10.6 μm wavelengths in aerosol clouds generated by burning of pyrotechnic mixtures is investigated. The results of transmission measurements and evaluated values of volume attenuation coefficient are presented for a few kinds of chloroorganometallic smoke-producing agents. An estimation of the laser ranging diminution by the pyrotechnic-derived smoke was carried out.
