Non-membrane optical microphone based on longitudinal modes competition
We propose and demonstrate a simple and cost effective non-membrane optical microphone (OM) consisting of only a standard erbium doped fibre amplifier (EDFA) and a 25 km of conventional single mode fibre (SMF) as the sensing medium. A photo detector is used for data acquisition. The proposed setup u...
