A Broadband Interferometric Fiber-Optic Hydrophone Enabled by a PPSU Mandrel and a Metamaterial Liner
Interferometric fiber-optic hydrophones are widely deployed in passive underwater acoustic detection systems due to their high sensitivity, broad dynamic range, and immunity to electromagnetic interference. However, their adoption in active acoustic systems has been largely constrained by the limited operational bandwi...
