Title: Jacques Chretien: Optical Fiber Pressure-Sensing Innovation
Introduction
Jacques Chretien is an inventor based in Champagney, France. His work includes an invention for measuring fluid pressure with an optical fiber and thermal sensing.
Latest Patents
Chretien is associated with 1 patent, titled “Optical Fiber Pressure Sensor Using Thermal Pressure Sensing.” The patent describes a pressure-measuring device with an optical fiber that has a thinned portion. A heating laser sends light into this portion, while a measuring system detects backscattered light produced by an interrogation wave. A processing unit uses that measurement to determine the pressure of the surrounding fluid, preferably a gas.
Career Highlights
Chretien’s listed professional affiliations include the French National Centre for Scientific Research (Centre National de la Recherche Scientifique) and Université Marie et Louis Pasteur.
Collaborations
His listed collaborators include Jean-Charles Beugnot and Adrien Godet.
Conclusion
Jacques Chretien’s patent presents an optical-fiber approach to pressure measurement, combining laser heating, backscatter detection, and signal processing.
