Data manual--FG-98A/H single-axis fiber optic gyroscope
◾ Product introduction
The FG - 98 a/H uniaxial optical fiber gyro is an optical, mechanical and electrical integration of the solid-state high precision and high precision in digital closed loop uniaxial optical fiber gyro, based on the sag principle, by the erbium-doped fiber optic light source, optical fiber coupler, photoelectric detector, integrated optical phase modulator, optical fiber sensing ring, circuit and structures.
It is iterated on the basis of FG-98 fiber optic gyroscope, inherited the classic design of FG-98 gyroscope, adopted higher production technological level, and improved performance comprehensively.It can be widely used in various navigation and guidance fields.
Classical navigation-class fiber optic gyroscopes.
