Abstract

New method of multimode fiber interferometers signal processing is suggested. For scheme of single fiber multimode interferometers with two exited modes the method based on using of special fiber unit is developed. This unit provides the modes interaction and further sum optical field filtering. As a result the amplitude of output signal is modulated by external influence on interferometer. The stabilization of interferometer sensitivity is achieved by using of additional special modulation of output signal. The achieved parameters for double mode scheme: temporary stability - 0.6% per hour, sensitivity to interferometer length deviations - 3.2 nm.
