1. Core Component Design
Light Source: This product uses Super Radiant Light Emitting Diode (SLD) or laser diode to ensure the stability and coherence of the output light signal.
Fiber Optic Coil: A low-loss, highly birefringent, bias-preserving fiber is used, precisely wound into a ring structure to enhance the Sagnac effect.
Photodetectors: Highly sensitive detectors are used to detect the phase change of optical signals and convert them into electrical signals.
Signal Processing Unit: Integrated high performance Digital Signal Processor (DSP) for real-time processing of optical signals and calculation of angular velocity.
2. Product advantages
Long life and low maintenance
Due to the all-solid-state design, fiber optic gyroscopes have no mechanical wear parts, long service life, and are virtually maintenance-free, significantly reducing the user's operating costs and maintenance efforts.
