摘要
The features of the amplitude modulation of guided radiation in single-mode fiber lightguides with a low normalized frequency when acted upon by seismic signals are investigated. It is shown that the sensitivity of sections of such lightguides to seismic shocks can reach 6.10(-4) g. This makes it possible to use them to construct fiber-optical measuring transducers, whose metrological characteristics enable them to be used to solve a wide range of geophysics problems.
