Methods for acoustic desensitization of fiber optic interferometer were studied as applied to the compensation interferometer (CIF) of a fiber optic phase sensor system. Materials with high mechanical loss factor were used for the fiber optic interferometer rack case. Also case acoustic conditioning measures and vibration isolation system based on steel springs were developed. Different types of fiber coating for acoustic desensitization were investigated. The best implementation provided up to 30 times (-29.8 dB) suppression of CIF undesirable acoustic sensitivity level.
