FIELD: measurement of parameters of accelerations and vibrations from natural and artificial sources. SUBSTANCE: two fibre-optical coils of interferometer are wound interference fit on side surfaces of two elastic cylindrical backings. Inertial mass is arranged between two elastic backings. Interferometer is matched with double-wave source of coherent light and two photodetectors through optical spectral divider. Outputs of photodetectors are connected to electron unit. Electron unit makes it possible to tune operation of interferometer to length of wave optimal from point of view of sensitivity and dynamic range of interferometer. Electron unit removes influence of changes of intensity of light source too. EFFECT: enhanced reliability of fibre-optical accelerometer. 4 dwg
