A low-cost and broadband-response fiber-optic hydrophone by using metal diaphragm reflection

摘要：

　　A broadband-response fiber-optic hydrophone based on Au-coated stainless steel diaphragm and an encoded narrowband filtering function based on the Fourier transform and matrix multiplication are demonstrated.Sensitivity of 0.13mV/Pa,0.19mV/Pa,0.11mV/Pa and 0.17mV/Pa can be achieved at 8 KHz,25 KHz,200 KHz and 1 MHz,respectively.The advantages of simple fabrication,broadband-response,low-cost,and linear response make our fiber-optic hydrophone a perfect candidate for enormous economical manufacturing.
