Abstract
A system for improvement of waveform transmission and event detection includes a first transducer configured to receive acoustic waveforms, and a first transducer processor and transmitter configured to invert the phase of the received waveforms of the first transducer and transmit the inverted waveforms via light to a second transducer. The second transducer is configured to receive light waveforms from the first transducer processor and transmitter, receive acoustic waveforms from the second transducer, convert the first transducer light waveforms and the second transducer acoustic waveforms into electrical waveforms, and transmit a combined electrical waveform onwards.
