High Dynamic Range Fog Gyroscope Sensor with RS422 Digital Communication

High Dynamic Range Fog Gyroscope Sensor with RS422 Digital Communication​

PRODUCT 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, and a digital closed-loop detection circuit is adopted to extract the optical path difference of clockwise and anticlockwise propagating light caused by the external physical angular rate, which is sensed by the optical fiber ring,At the same time, the voltage signal converted from the optical path difference signal is used for closed-loop feedback and control to realize the modulation and demodulation of the signal and achieve the purpose of angular velocity signal detection.

Composition

a) The optical path unit comprise an SLD light source, an optical fiber re, an integrated optical phase modulator, an optical fiber coupler and an optical detector;

b) The circuit unit comprises a light source driving circuit and a detection and control signal circuit board;

c) Gyroscope structural parts.

Product structure and features

The gyroscope structure adopts a typical optical fiber ring structure design scheme, and from the miniaturization integrated design, structural stability (resistance to shock and vibration), anti-resonance, structural symmetry, ease of installation and thermal design (temperature Characteristics) and other aspects were considered, and the existing structure of the gyro was optimized and designed.

Product Usage

The F60 fiber optic gyroscope has the characteristics of long life, strong shock and vibration resistance, large measurement range, high bandwidth, instant start, no drift caused by acceleration, and wide accuracy coverage. It can be widely used in ships, aircraft, and vehicles and Robot navigation, positioning and orientation, stability control and other fields.
