FIELD: measuring.
SUBSTANCE: invention relates to the field of navigation instruments and can be used to determine the wave solid-state gyroscope resonator parameters. Device comprises a body, a rod with a seat for installing a resonator of a wave solid-state gyroscope, a rotary device, an excitation sensor made in the form of a direct current solenoid, two measurement sensors, each of which comprises an optical radiation source, a photodetector, an optical insulator, a collimating device, a mirror, a fibre-optic splitter with four optical channels, a signal control and processing unit, a block of peripheral input and output devices. Frequency splitting is measured by sensors made in the form of interferometric measuring channels.
EFFECT: high accuracy of determining natural frequency splitting when checking resonators of wave solid-state gyroscopes.
