Fiber optic gyroscope is the fiber angular velocity sensor, which is the most promising one among various fiber optic sensors. The fiber optic gyroscope, like the ring laser gyroscope, has the advantages of no mechanical moving parts, no warm-up time, insensitive acceleration, wide dynamic range, digital output, and small size. In addition, the fiber optic gyroscope also overcomes the fatal shortcomings of ring laser gyroscopes such as high cost and blocking phenomenon. Therefore, fiber optic gyroscopes are valued by many countries. Low-precision civilian fiber optic gyroscopes have been produced in small batches in Western Europe. It is estimated that in 1994, the sales of fiber optic gyroscopes in the American gyroscope market will reach 49%, and the cable gyroscope will take the second place (accounting for 35% of sales).

The main function of EDFA in the optical fiber communication system is to extend the relay distance. When it is combined with wavelength division multiplexing technology and optical arc technology, it can realize ultra-large capacity and ultra-long distance transmission.

The fiber optic sensor network has three basic components, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where one optical fiber connects many sensors together so that many sensors can share the light source to realize network monitoring. Then there is the smart fiber optic sensor. The multi-point optical fiber sensor is a grating from the outside, and periodic intervals are found through ultraviolet irradiation. When an optical fiber is incident, if the wavelength of the optical fiber is exactly twice the interval, the light wave will be strongly reflected, and if the optical fiber is subjected to temperature changes or strains, the reflected wavelength will change. This kind of sensor There can be many on one fiber, and it can be used for a variety of sensing applications by connecting them.
