◾ 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!
