FIELD: measuring technology.
SUBSTANCE: invention relates to measuring technology, namely to vibration conversion devices. The device of the spectral vibration converter contains a housing element and an inertial mass made in the form of a quartz membrane with a massive rigid center. The massive rigid center is made inside the closed cavity of the membrane. From the outside, an optical fiber with a Bragg fiber lattice is fixed on opposite ends of the membrane in such a way that, on one side of the Bragg fiber lattice, the optical fiber is fixed on one end of the membrane, and on the other side on the other end, with the possibility of transmitting a vibration effect to the optical fiber section containing the Bragg fiber lattice, causing small deflections of one of the ends of the membrane due to vibrations of its rigid center.
EFFECT: increase in the accuracy of the spectral vibration converter.
