A software-defined coherent fiber optic sensor for manufacturing machine diagnostic

A new approach to fiber optic sensing is proposed which combines the multi-parameter sensing capabilities of standard optical fibers with recent advances in demodulation schemes and digital signal processing (DSP) for coherent optical communication systems. A common HW that can fulfil multi-purpose monitoring requests is obtained, where the information related to a specific physical parameter is recovered through a proper tailoring of the DSP. The fiber optic sensor thus becomes Software-Defined by the customer specific requirements, proving a cost-effective and versatile diagnostic solution for the achievement of sustainable predictive maintenance strategies in the manufacturing industry.
