Published Date: 2023-02-20
With its unique advantages, fiber optic gyroscopes have broad prospects for development in the field of precision physical quantity measurement. Therefore, exploring the influence of optical devices and physical environment on the performance of fiber optic gyroscopes and suppressing relative intensity noise has become the key technology for realizing high-precision fiber optic gyroscopes. With the continuous deepening of research and the realization of high-precision miniaturized integrated fiber optic gyroscope will be greatly developed and applied.

The fiber optic gyroscope is a sensitive element based on a fiber optic coil, and the light emitted by a laser diode propagates along the fiber optic fiber in two directions. The difference in the light propagation path determines the angular displacement of the sensitive element. Modern fiber optic gyroscope is an instrument that can accurately determine the orientation of moving objects. It is an inertial navigation instrument widely used in modern aviation, navigation, aerospace and national defense industries. Its development has a great impact on a country's industry, national defense and other The development of high technology has very important strategic significance.

Traditional inertial gyroscopes mainly refer to mechanical gyroscopes. Mechanical gyroscopes have high requirements on process structures and complex structures, and their accuracy is restricted by many aspects. Since the 1970s, the development of modern gyroscopes has entered a new stage.

Compared with the traditional mechanical gyroscope, the fiber optic gyroscope has the advantages of all solid state, no rotating parts and friction parts, long life, large dynamic range, instant start, simple structure, small size and light weight. Compared with the laser gyroscope, the fiber optic gyroscope has no lock-up problem, and does not need to precisely process the optical path in the quartz block, so the cost is relatively low.

The realization of the fiber optic gyroscope is mainly based on Segnik's theory: when the light beam travels in a circular channel, if the circular channel itself has a rotational speed, then the time required for the light to travel along the direction of rotation of the channel is shorter than that of the light along the channel. It takes more time to travel in the opposite direction of the turn. That is to say, when the optical loop rotates, in different traveling directions, the optical path of the optical loop will change relative to the optical path of the loop when it is stationary. By using this change of optical path, the phase difference of two optical paths or the change of interference fringes can be detected, and the rotational angular velocity of the optical path can be measured. This is the working principle of the fiber optic gyroscope.

The gyroscope sensor industry belongs to the "Optoelectronic Device Manufacturing" ( C3976) and "Manufacturing of Sensitive Components and Sensors" (C3983). According to the "Guidelines for the Industry Classification of Listed Companies" (revised in 2012) promulgated by the China Securities Regulatory Commission, it belongs to the "computer, communication and other electronic equipment manufacturing industry" (C39).

In the international market, fiber optic ring suppliers include Coherent, iXblue, Luna Innovations, etc., among which Coherent is the leading enterprise in the fiber optic ring market. my country's fiber optic gyroscope industry started late. Compared with foreign companies, my country's strength in the research and development of photovoltaic gyroscopes and the production of core components is relatively weak. Domestic fiber optic gyroscopes are mainly low-end products, and high-end fiber optic rings still rely on imports.

Benefiting from the expansion of fiber optic gyroscope application fields and the increase of enterprises, the fiber optic ring market will grow accordingly. From 2016 to 2021, the global fiber optic ring market will maintain a compound annual growth rate of more than 5.0%, and will reach 6,800 in 2021. It is estimated that the global optical fiber ring market will maintain a growth trend from 2022 to 2026 and reach 85 million US dollars in 2026.

The fiber optic gyroscope is one of the mainstream devices in the field of inertial technology research. With the improvement of the technical level, the application scale of the fiber optic gyroscope will continue to expand. As the core component of the fiber optic gyroscope, the market demand for the fiber optic ring will also increase accordingly. At present, my country's high-end optical fiber ring still needs to be imported. Under the general trend of domestic substitution, the core competitiveness and independent research and development capabilities of my country's optical fiber ring enterprises still need to be further enhanced.

At present, fiber optic rings are mainly used in the military field, but as the application of fiber optic gyroscopes expands to the civilian field, the proportion of fiber optic rings in civilian applications will further increase. Globally, the technical level of fiber optic gyroscopes in the United States and Japan is at the leading level in the world. Related suppliers include Honeywell, KVH, Mitsubishi Precision, Sumitomo Electric, etc. In China, manufacturers of fiber optic gyroscopes include CSIC 717, AVIC 618 Institute, Hongfeng Machinery, etc. As one of the important components of the fiber optic inertial navigation system, the fiber optic gyroscope market is expected to reach 3.782 billion yuan in the future.

The direction of development of fiber optic gyro: one is to develop in the direction of higher precision and higher reliability, providing high-precision inertial components for aerospace, aviation, and navigation; Develop in the direction of ultra-miniaturization, providing rugged and cheap inertial sensors for tactical applications; the third is to develop in the direction of multi-axis.
