Abstract :
The recent results of the design and application of laser interferometer array for recording the seismic and acoustic strains of the earth ground are presented. The system contains the number of precise laser interferometers with the space distanced measuring arms. Interferometer gauges with the base length from 5 m up to 300 m have been used. The design and operation of constituent laser interferometer units, data exquisition system, and preliminary results of their using to the real earth strain observation in seismic and acoustic frequency bands are discussed.
