The interferometer of scattered radiation is employed for the detection of the external acoustic action upon an optical fiber. A method for the demodulation of the scattered field using the phase diversity procedure is proposed. The possibility of the fading regions in the demodulated signal is demonstrated, the reasons for such an effect are analyzed, and the methods for its elimination are proposed.
