TG-40 three-axis integrated fiber optic gyroscope

◾ Product introduction
TG-40 three-axis integrated fiber optic gyroscope is a full solid-state high-precision digital closed-loop 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 miniaturized inertial measurement systems, and has the characteristics of small size, high precision, high reliability, and flexible structure. The installation position of quartz accelerometer or MEMS accelerometer is included, and it can be produced according to the platform designed by customers.
TG-40 is the best choice for small inertial measurement systems!
