◾ Product introduction
FG-30 single-axis fiber optic gyroscope is an all-solid-state
high-precision digital closed-loop medium-low single-axis fiber
gyroscope that integrates optics, machinery and electricity. Based
on SAGNAC principle, it is composed of SLD light source, optical
fiber coupler, photoelectric detector, integrated optical phase
modulator, optical fiber sensing ring, circuit and structures.
It is designed for servo stabilization platform with the features
of small volume, high update rate, low delay, low noise, high
bandwidth and so on. It is the ideal choice of medium and low
precision angular rate sensor and can be used widely in various
types of stable platform.
