Main Features
The DFOG fiber optic gyroscope is a cost-effective standard
low-precision fiber optic gyroscope. Compared to 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
