Abstract

The paper presents the description and estimation of the sensitivity of laser nanobarograph, laser strainmeter, and laser meter of the hydrosphere pressure variations that have been developed on the basis of modern laser-interference methods using frequency-stabilized lasers. These sets are designed for study of the laws of generation, dynamics, and transformation of oscillations and waves of low-frequency and super low-frequency ranges on the boundary of the "atmosphere-hydrosphere-lithosphere" system. Some experimental results of the study of the atmospheric process influence on the lithospheric ones are given. A significant correlation between the atmosphere pressure variations and changes of the earth crust microdeformation level on tide frequencies and their harmonics has been revealed.
