F70-98 single axis closed-loop FOG
F70-98 FOG
F70-98is a high accuracyangular speed sensor integrated with light, mechanism and eletricity. it is based on Sagnac effect and close loop control test technology. it tests, processes and feedbacks by the phase difference produced by two oppsite transmission light, realising the whole close loop process.the item is mainly composed by optical path units, circuit units and structural unit. it has simpler structure, no moving parts, no wearing parts, quicker start, smaller volume and ligher comparing with electromechanical gyro.

DESCRIPTION
----------------------------------------------------------------------------------------------------------------------------
This product is an inertial angular rate sensor based on the optical Sagnac effect, which is used to measure the angular rate of the
carrier along the sensitive axis of the product. The angular rate sensing unit of the product is an optical fiber ring, a digital closed-loop
detection circuit is adopted to extract the optical path difference of clockwise and counterclockwise propagation light caused by the
external physical angular rate, which is sensed by the optical fiber ring, and meanwhile, a voltage signal converted from an optical
path difference signal is subjected to closed-loop feedback and control, so that the modulation and demodulation of the signal are
realized, and the purpose of angular rate signal detection is achieved.
FEATURES
----------------------------------------------------------------------------------------------------------------------------
This product consists of two parts: optical angular velocity sensitive unit and signal detection, providing uniaxial angle increment
information and internal temperature information.
