Bragg Networks are sensors on optical fiber for the measurement of deformation, vibration, temperature, inclination and other parameters.
A Bragg network is a periodic or aperiodic disturbance of the effective refractive index in the core of an optical fibre.
Normally, the disturbance is approximately periodic over a certain length of, for example, a few millimetres or centimetres, and the period is of the order of hundreds of nanometres.
Applications of BRAGG technology:
- Continuous temperature monitoring.
- Security in case of detection of vandalism or intrusion in critical infrastructures.
- Control mechanisms.
