Project manager – Optical in-situ measurement
An optical in-situ monitoring of rapid pressure changes should be developed for industrial applications in a difficult environment. This is based on a Bragg grating in a glass fibre. The laser wavelength was controlled on the grating. A change in the lattice constant caused a variation in the light reflection.
We designed this method as part of a CTI project with EMPA in Thun. In addition, we developed an evaluation algorithm based on machine learning.
The test with a prototype has proven the suitability of this method.
