◾ Product introduction
DG-20B dual-axis fiber optic gyroscope is a full solid-state
high-precision digital closed-loop medium and low uniaxial fiber
optic gyroscope integrating optics, mechanics and electricity.
Based on the principle of Sagnac, it is composed of SLD light
source, fiber coupler, photodetector, integrated optical phase
modulator, fiber sensing ring, circuit and structure.
It is specially designed for the servo stable platform, and has the
characteristics of small volume, high update rate, low delay, low
noise, high bandwidth and so on. It is an ideal choice for low- and
medium-precision angular rate sensors, and can be widely used in
various types of stable platforms.
