Abstract
A novel interrogation technique for fibre Bragg gratings, based on the self-mixing effect in strong feedback regime and intensity detection, is demonstrated through experimental measurements. The application of an appropriate spectral estimator permits transferring the analysis into the frequency domain, leading to the realisation of a power drift-tolerant strain sensor.
