For industrial application in a difficult environment, an optical in-situ monitoring of fast pressure changes should be developed. This is based on a Bragg grating in an optical fiber. The laser wavelength was controlled to the grating. A change in the grating constant caused a variation in the light reflection.
Within a CTI project with EMPA in Thun, I designed this method. In addition, we developed an evaluation algorithm based on machine learning (AI).
A test with the prototype proved the suitability of this method.
