Abstract

The experimental validation of the fiber interferometer signal demodulation method based on the additional phase modulation and digital signal processing is presented. The results obtained for various target signal shapes and different number of samples per modulation period demonstrated the effectiveness of the processing algorithms applied to the interference systems.
