Abstract

In this paper we report the development and field test of a high sensitivity 3C fiber laser geophone for seismic acquisition application. When the fiber laser geophone senses the seismic signal, its output wavelength is proportionate to the seismic signal. By detecting the wavelength shifts using interferometric demodulation method, the micro-seismic signal can be detected. We are presenting field test results for the 3C fiber laser geophone array system and comparing its performance with regular exploration geophones. The detailed information of the acquired seismic signals, e.g. waveform, frequency spectrum, and wavelet are analyzed for assessing their performance. The 3C fiber laser geophone has advantages of wide bandwidth and good high-frequency response.
