FG-50 single-axis fiber gyroscope is an all-solid-state
high-precision digital closed-loop medium and 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.
As a classic model, continuous iteration and upgrade, with small
size, high update rate, low delay, low noise, high bandwidth, super
adaptability in the environment and other characteristics. It is
the ideal choice of medium and low precision angular rate sensor
and can be used widely in various types of stable platform and
navigation guidance field.
