Abstract
This article gives an overview of results achieved in process of design, developing and using of data acquisition and control systems for LSM (long-base strainmeters) and other devices based on Michelson laser interferometer. Such control systems are also used in other types of laser-interference instruments that provide the study of geodynamic processes in a broad frequency range. It’s shown that the effective means for control of external factors in geophysical measurements using LSMs are the same-type laser-interference instruments. The geophysical laser-interference complex is described in this paper as the basis for the construction of interregional space-separated measuring systems. The efficiency of laser-interference meters based on the Michelson interferometer is shown for taking into account the influence of external factors during geophysical measurements using laser strainmeters. A recording system of a strainmeter based on a Michelson interferometer is described, which makes it possible to obtain high sensitivity and record high-frequency oscillations (up to 2 kHz). The advantages of using this control system over the previous versions are noted: the optical scheme of the proposed interferometer contains fewer parts, and the recording system is more reliable and has less power consumption.
