Description

technical field

[0001] The invention relates to the technical field of optical fiber sensors, in particular to a fiber grating sensor sensitivity enhancement structure. Background technique

[0002] Compared with the corresponding conventional sensors, optical fiber sensors have obvious advantages in terms of sensitivity, dynamic range, reliability, etc., especially in the fields of construction, petroleum, and military applications.

[0003] Optical fiber sensor is an instrument that uses the light transmission characteristics of optical fiber and various modulation effects generated by its interaction with the surrounding environment to detect physical quantities such as temperature, pressure, and strain in the surrounding environment. Compared with traditional resistive sensors, it has the following main advantages: high pressure sensitivity, no electromagnetic interference, light weight, high temperature resistance, compact structure, high reliability, and information se...
