Product Details
1. Structural Composition
The FOG is mainly composed of the following core components:
Light source (usually a superluminescent light emitting diode SLD):
provides light with low coherence to reduce coherent noise.
Fiber optic ring (a few hundred to a few thousand meters): used to
guide the light propagation and create an interference effect.
Optical beam splitter (coupler): divides light into clockwise and
counterclockwise directions.
Photodetector: receives the interfered light signal and converts it
into an electrical signal.
Signal processing circuit: calculates the phase difference and
outputs the angular velocity signal.
2. Product Advantages
Fiber optic gyroscopes have no moving parts and work entirely on
the basis of optical principles. They are extremely resistant to
external electromagnetic interference, vibration and shock, making
them suitable for use in harsh environments such as aerospace,
marine and industrial scenarios.
