An original approach to studying acoustooptic interactions at infralow frequencies using seismic vibrators is proposed. The authors in numerous and natural experiments has been proved that such sources can radiate low-frequency acoustic oscillations, propagating in the atmosphere up to hundreds of kilometers from the source. High-precision metrological properties of vibrators on frequency-time characteristics open up possibility for investigating acoustooptic interactions at infralow frequencies. An acoustooptic system developed by the authors is described. The system consists of the CV-40 vibrator, an optical bench with a laser emitter with a radiation power of up to 6 W at a wavelength of 850-930 nm and a pulse repetition rate of 1 kHz, a set of acoustic measurement stations, and a meteorological station. The results of natural and test experiments on acoustooptic interactions are presented. On sound frequencies as a source of acoustic oscillations were used dynamics with capacity of radiation 20 W. Results of comparative registration of acoustic fluctuations by means of piezoelectric sensors of pressure, and also optical sensors are resulted. In the course of measurements pressure sensors settled down along a measuring laser beam.
