HTS-FB2 fiber optic gyroscope (FOG) is an
inertial angular rate sensor based on the optical Sagnac effect, which is used
to measure the rotational angular velocity of the carrier along the sensitive
axis. A digital closed-loop detection circuit is used to extract the optical
path difference of the clockwise and counterclockwise propagating light caused
by the external physical angular velocity of the fiber ring, and the optical
path difference signal is converted into a voltage signal for signal modulation
and demodulation, and closed-loop feedback and control are realized to achieve
the purpose of real-time angular velocity signal detection.
Functions: The HTS-FB2 fiber optic
gyroscope consists of an optical angular velocity sensitive unit and a signal
detection unit, providing single-axis angular increment information and
internal temperature information.
Applications: optoelectronic pods, flying
platforms, strapping inertial navigation, inertial measurement systems, optical,
photographic instruments, platform stabilization devices, inertial measurement
instruments and other applications.
