A Demodulation Circuit Utilized for Fiber Seismic Signal Detection System
A demodulation circuit designed for optical fiber seismic signal detection system is proposed and experimentally demonstrated. The system based on an edge filter demodulation methods. The pre-amplifier TLC2201, divider AD734 and LabVIEW software are detailed described and employed in the circuit to improve the SNR and simplify the system structure.
