High-speed acquisition optical fiber sensor

The invention is within the optical fiber sensor technology, and in particular, sensors that measure physical perturbations (temperature, mechanical vibrations, pressure), where the wavelength of the reflected light responds to these parameters, such as fiber Bragg grating (FBG) sensors or Fabry-Perot sensors. The sensor proposed in the invention allows reading these sensors at sampling rate beyond hundreds of kHz, which is not possible using commercially available sensors, but necessary in many applications.

The patent is developed by a Proof od Concept funded by MISE in the JUMP project, (info)
