Detection of Weak Seismic Waves in Land–Sea Interface by Fiber-Optic Interferometric Accelerometers
摘要
Abstract
The possibility of detection of weak seismic waves in land–sea interface by horizontal fiber-optic interferometric accelerometer is experimentally demonstrated. The use of a passive phase demodulation method with a 3 × 3 fiber-optic splitter ensures high stability of the accelerometer.
