Description

technical field

[0001] The invention relates to a fiber grating sensor. In particular, it relates to the manufacture of a new type of distributed optical fiber sensor mirror that can be applied in practice, is simple, reliable, stable, and high-precision, and can produce wide bandwidth, low reflectivity, consistency, and uniformity. Background technique

[0002] Fiber optic and fiber grating sensors are new types of sensors that have developed rapidly in recent years. Fiber optic and fiber grating sensors can integrate information sensing and transmission. Compared with traditional sensors, it has many advantages: such as explosion-proof, anti-electromagnetic interference, anti- Corrosion, shock resistance, high temperature resistance, small size, light weight, flexible and convenient, especially can be used in harsh environments.

[0003] Distributed optical fiber sensing system is the best detection method for leaks in dam projects, strains of large buildings, oil pipelin...
