HBM FiberSensing Optical Solutions

Optical Measurement Solutions based on FBG Sensors

Bringing light to measurement

Gain from the many new possibilities provided by optical sensor technology based on Fiber Bragg Gratings - and HBM's proven reliability.

HBM FiberSensing is proud of having addressed hundreds of different monitoring projects around the world and delivered thousands of sensors and measurement units throughout the years.

Reliably and safely test innovative materials with high levels of strain or high numbers of load cycles, high electromagnetic stress or in highly explosive environments.

Case Studies

What are the measuring principles of a fiber Bragg grating?

The principle of measurement of the fiber Bragg grating may be briefly explained as a periodic microstructure that selectively reflects wavelengths. You can learn more about it here in this article.

What is a fiber Bragg grating?

A fiber Bragg grating is just a few millimeters long, highly sensitive and very reliable. We explain the most important properties for you in an article.
