PhD: Cryogenic temperature measurements using fiber Bragg gratings (MOPERE team)

Location: Laboratoire Hubert Curien, Saint-Etienne, France

The main objective of the PhD, conducted in collaboration with a very prominent French industrial company in the aerospace field, is to identify and test a sensing chain based on Bragg grating technology (FBG) and optimized for cryogenic temperature measurement. The innovative tasks involve the various elements of the measurement chain, including the optical fiber, the type of Bragg grating and the interrogator. The aim of the thesis, which will be mainly experimental, will be to design and manufacture the sensors, and to determine and optimize the achievable performance according to the implementation conditions for different industrial use profiles.

Prerequisites:
