摘要：

Behavior of a signal of the Rayleigh scattering of a laser radiation in air was studied depending on the parameters of an ultrasonic wave excited in the region of observation. It is shown that the presence of an ultrasonic wave in this region provides for a spatial resolution in the direction of observation with respect to the energy parameters of the laser radiation from the Rayleigh scattering measured at the sound frequency. The minimum intensity of laser radiation and the spatial resolution are estimated for a particular frequency and intensity of sound. (C) 2000 MAIK "Nauka / Interperiodica".
