Main Features
The DFOG-A fiber optic gyroscope is a standard cost-precision
fiber optic gyroscope with excellent cost performance.
Compared with other domestic products of the same type, it
has superior bias stability and temperature characteristics. At
the same time, it has the characteristics of light weight,
convenient use, good magnetic shielding and mature technology.
It has been widely used in the fields of stability control,
navigation guidance and attitude measurement.
Typical applications
Optical interferometer、 Optical Coherence Tomography、 Coherent telecommunications、 Spectrum analyzers、 Radar calibration, Optical network testing
