STG-60A
Fiber Optic Inertial Products
Product Introduction
STG-60A is a fully solid-state, digital closed-loop, integrated three-axis fiber optic gyroscope. Based on the SAGNAC principle, it consists of an SLD light source, fiber coupler, photodetector, integrated optical phase modulator, fiber sensing coil, circuit, and structure. It is specially designed for miniaturized inertial measurement systems, featuring compact size, high precision, high reliability, and flexible structural design, and can be customized according to the structure designed by customers. TG-40 is the best choice for small inertial measurement systems!
