1510-1590nm  Sensing  Fiber  Bragg  Grating

The optical fiber grating, as a diffraction grating formed by periodically modulating the refractive index of the fiber core along the axial direction through certain methods, possesses numerous notable characteristics and a wide range of applications.

Broad Measurement Range: Optical fiber gratings can measure a wide range of physical quantities, including temperature, pressure, strain, stress, flow rate, velocity, current, voltage, liquid level, and liquid concentration.

Optical Fiber Sensing: Due to their unique advantages such as electromagnetic interference resistance, corrosion resistance, and high sensitivity, optical fiber grating sensors have found widespread application in various fields, including aviation, aerospace, chemistry, pharmaceuticals, materials industry, water conservancy and electricity, shipbuilding, and coal mining. They play a significant role in structural monitoring, particularly in civil engineering fields such as buildings, bridges, and dams.
