Measuring with light

We use fiber optics sensors in combination with the most advanced and interrogator systems based on Photonic Integrated Circuits using spectrometry and interferometry principles for improved resolution, minitiaturization.

PRINCIPLE

Over the last years, fibre optic sensors based on Fibre Bragg Grating (FBG) technique, have been developed. The basic principle is: light is sent through a fibre optic cable and partially reflected by FBGs. A temperature change of the fibre causes a shift in wavelength of the reflected light, which can be measured very precisely and translated into temperature values.

INTEGRATED PHOTONICS

An Application Specific Photonic Integrated Circuit (ASPIC) is an optical chip designed for a dedicated purpose. Similar to electronics, ASPICs allows a variety of solutions, all based on a small set of components.
