Ordinary sensing grating


1.Basic principles

By utilizing the strain, temperature, and refractive index sensitivity characteristics of fiber Bragg gratings (FBGs), flexible and versatile designs can be combined with different structural designs, materials, and optical effects to achieve sensing and measurement of various parameters such as strain, temperature, refractive index, humidity, tilt angle, bending, wind speed, acceleration, vibration, and load.


2.production process

After peeling off the coating layer on a regular single-mode fiber, a phase mask template is used to engrave a grating with high reflectivity, which can be coated again.


3.Product advantages

Strong reusability, small size, light weight, long lifespan, resistance to electromagnetic interference, chemical corrosion, and long-distance transmission of sensing signals.       

4.Typical applications

In the fields of intelligent buildings, intelligent transportation, environmental monitoring, engineering environmental monitoring, temperature/fire monitoring, aerospace, navigation, and military.
