Abstract
The problem of measuring the spatiotemporal and energy parameters of acoustic infrasonic oscillations in the atmosphere is considered based on the placement of laser and fiber lines in geoecological monitoring zones. The measurements are based on the phenomenon of acousto-optical transformation at infralow frequencies associated with the influence of an external acoustic wave field on the characteristics of the propagation of laser pulse beams in this field. Background and anthropogenic atmospheric acoustic processes are used as external field sources. The measured parameter is the fluctuation of the phase (frequency) of the atmospheric optical signal relative to the reference optical fiber signal. The characteristics of the atmospheric fiber laser system and some results of experiments on assessing the statistics of fluctuations in the phase of atmospheric laser pulses and the parameters of infrasound fields in a given atmospheric monitoring zone are presented.
