Abstract

Two 16-element fiber-optic seismometer arrays based on combined wavelength- and time domain multiplexing technology have been designed and investigated, followed by a field test, which is focused on the sensitivities of the sensors and correlation of the signal. The field test shows that the consistency of the sensitivities is pretty good, though the fluctuation of sensitivities at different frequencies should not be ignored. The method to calculate the correlation of two sensors is presented briefly and the results show an acceptable high level. The field test indicates that it’s available to use the arrays in practical applications of micro-seismic.
