Fiber Bragg Gratings (FBGs) are created by exposing an optical fiber to a periodic pattern of intense laser light, resulting in a permanent refractive index change that forms a grating. This grating acts as a wavelength-selective mirror, reflecting a distinct Bragg wavelength.

When a fiber with multiple FBGs is illuminated with broadband light, each grating reflects light at different Bragg wavelengths, allowing for spectral detection. Manipulating the fiber through strain and temperature changes leads to measurable shifts in the Bragg wavelength, enabling accurate calculations of strain and temperature. Additionally, FBGs can be used to derive measurements for force, pressure, acceleration, vibration, and displacement.

Our range of high-quality Fiber Bragg Grating sensors offers significant advantages, including high fatigue limits, multiplexing capabilities, and immunity to electromagnetic interference, making them ideal for measuring strain, force, temperature, pressure, and shape.

Fiber Bragg Gratings (FBGs) offer numerous advantages, including immunity to electromagnetic interference, even from lightning. As intrinsically passive devices, FBGs require no electrical power, making them suitable for high-voltage and potentially explosive environments. Their lack of power consumption eliminates self-heating effects, which is critical when measuring low thermal conductivity materials.

FBGs can be read over long distances without the need for amplification, and multiple FBGs can be monitored in series on a single optical fiber without a return fiber. Advanced interrogator techniques enable the use of over 900 – 1k FBG sensors on a single fiber. Additionally, the glass composition of FBGs provides excellent corrosion resistance, enhancing their durability in various applications.
