Dolgikh G.I., Valentin D.I., Batyushin G.N., Dolgikh S.G., Kovalev S.N., Koren' I.A., Ovcharenko V.V., Yakovenko S.V. «Seismoacoustic hydrophysical complex for monitoring the atmosphere–hydrosphere–lithosphere system» Приборы и техника эксперимента, 45, № 3, с. 120-122 (2002)

The seismoacoustic hydrophysical complex intended for investigation of the interaction of geospheres wave fields in a frequency range from 1 μHz to 1 Hz is described. The complex consists of a shorebased system of laser strain meters, laser nanobarograph, bottom station with a hydrophone and a temperature-sensitive element, weather station, and seismoacoustic radiator. The use of modern laser-interferometry methods provided a deformation sensitivity of ≈10^–10 and an atmospheric-pressure sensitivity of 10 mPa.

An analyzer is designed for analyzing both continuous and impulse signals in a wide frequency range. The analyzer fields of application are: development of wide-band spectra analyzers to study on different physical processes, radioastronomy investigations, development of panning radioreceivers operating in real time scale. The analyzer is connected in the spatial integrating circuit and comprises optical radiation source, prismatic optical beam shaper, acoustooptical modulator, Fourier long-focal length lens, photoreceiver, read-out and signal processing circuit.
