摘要：
The results of investigation of a new type of the optical-fiber coherent phase-sensitive reflectometer with two different optical frequencies of probing pulses are presented. The use of pulses with different optical frequencies allows recovering of the signal of an external action on the reflectometer optical fiber by means of phase diversity technique. The applicability of the proposed technique is justified theoretically and experimentally.
