Abstract

An application of a measuring system based on fiber optic Sagnac interferometer for measurements of phase characteristics of vibrating elements is described. Due to the application of a set of phase- polarization detectors, such a system may be applied to obtain phase characteristics of measuring heads used in fiber optic interferometry. Used instrumentation allows to study elements in the frequency range from 100 Hz to 1.4 MHz.
