Fiber Bragg Gratings (FBG) / Sensors systems
IDIL Fibres Optiques provides a wide range of Fiber Bragg Gratings (FBG sensors) designed according to customers’requirements.
Fiber Bragg Gratings (FBG) summary
IDIL Fibres Optiques can work from single-mode, multi-mode and polarization maintaining fibers and supply every type of connectors. Furthermore we calculate and design the profile of FBG sensors. We also characterize and realize multiplexed FBG sensors (cf opposite) with several gratings on the same optical fiber (from one to about twenty) which can be close as a few millimeters or separated by a few kilometers. Finally we offer athermal, small size and weight packaging.
Our FBG sensors lead to numerous applications in the fields of optical sensors (temperature, strain, pressure…). Our technology is ideal for structural health monitoring of aircraft, buildings and dams; improving turbines and industrial equipment efficiency, detecting instabilities within tunnels and power plants, etc.

Fiber Bragg Gratings technology consist of selecting only a very precise wavelength thanks to an optical mirror which was firstly photo imprinted by UV beam pattern into an optical fiber.
When the optical fiber is stressed or when its temperature is modified, the wavelength varies proportionally.
