The development of fiber optic gyroscope is changing with each passing day. Not only are scientists enthusiastic about this, but many big companies have joined the ranks of research and development because of their good market prospects. Because of the ideal application of fiber optic gyro in mobile carrier and military field, the military of every country has invested a lot of money and energy.           

At present, some developed countries, such as the United States, Japan, Germany, France, Italy and Russia, have made great progress in the research of fog. Some low and medium precision gyroscopes have been commercialized, and a few high-precision products have been debugged in the military.

The first generation of fiber optic gyro has been put into production in a few countries, such as the middle and middle generation fog and the Russian navy. The research of fog in China started relatively late, but with the efforts of the majority of researchers, the gap between China and developed countries has been gradually narrowed.

According to the current information, the development accuracy of fog in China has reached the low and medium precision requirements of INS, and some technologies have even reached the level of similar products abroad. However, most of the domestic research is still in the laboratory stage, there is no product, there is still a gap between the application. So we still have a long way to go.
