In addition to the above applications, fiber grating sensors have also been applied in other fields, such as:
(1) Using the principle that different temperatures will cause different fluorescence delay times in crystal materials, the split point detection sensors made are widely used in industry and medicine;
(2) Optical fiber tomography technology, according to different principles and applications, can be divided into optical coherence tomography (OCT) and optical process tomography (OPT);
(3) Fiber optic gyroscope and inertial navigation system. The three-axis inertial navigation system for helicopters manufactured by Honeywell of the United States for the U.S. military is only 86mm in diameter. Japan's Mitsubishi Precision Co. and the Space and Aerospace Institute have designed and manufactured for the Japanese MV rocket system. Inertial navigation system.
In short, the application of fiber grating sensors is an ascendant field with very broad development prospects.
