Abstract. A fiber-optic accelerometer based on the Mach-Zehnder interferometer with an active working point stabilization system is developed. Results of field tests of the accelerometer, confirming the possibility of its use for monitoring of natural and man-made objects, are presented.
Keywords: fiber-optic interferometer, seismic signal, accelerometer
