DG-20B dual-axis fiber optic gyroscope

◾ 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.
