Product Description
Products Description
This product is an inertial angular rate sensor based on optical Sagnac effect, which is used to measure the rotation angular velocity of the carrier along the sensitive axis. The digital closed-loop detection circuit is adopted to extract the optical path difference of the clockwise and counterclockwise propagation light caused by the external physical angular velocity, which is sensed by the optical fiber ring, meanwhile, the optical path difference signal is converted into a voltage signal to carry out the modulation and demodulation of the signal, and the closed-loop feedback and control are realized to achieve the purpose of real-time angular velocity signal detection.
Function
The product consists of an optical angular velocity sensing unit and a signal detection unit, and provides single-axis angular increment information and internal temperature information.
ApplicationThe product is mainly applicable to the application of electro-optical gimbal,flight control platform, strapdown inertial navigation, inertial measurement system, optical/photographic instrument, platform stabilization device, inertial measurement instrument, etc.
Composition
The main components of the product are as follows:
- The optical path unit comprise an SLD light source, an optical fiber coil, an integrated optical phase modulator, an optical fiber coupler and a photoelectric detector;
- Circuit unit: light source drive circuit, signal detection and control circuit;
- Gyroscope structural parts.
