1. Product Core Technology
The 3-axis integrated fiber optic gyroscope integrates a number of
advanced technologies to ensure high accuracy, low drift and
stability:
A. Fiber optic ring technology: high quality fiber optic
manufacturing, optimized fiber optic winding process to reduce
temperature drift and fiber optic non-uniformity effects.
B. Closed-loop control: Digital Signal Processing (DSP) and
closed-loop modulation technology to improve gyro output stability
and dynamic range.
C. High-precision signal processing: low-noise photodetector and
signal filtering algorithms to improve signal quality and reduce
the impact of noise.
D. Temperature Compensation Algorithm: Integrated temperature
sensor and temperature compensation algorithm to ensure that it can
still maintain high precision measurement in different
environments.
E. High Reliability Structure Design: Adopting anti-shock and
anti-vibration design to ensure stable operation even in harsh
environments.
