Zusammenfassung:The present invention relates to an apparatus and a method for fiber optic perturbation sensing, in which it is possible to easily confirm whether an intrusion is occurred, an intrusion position, and an intrusion object by dividing an optical signal output from the optical signal generation unit, progressing the divided optical signals to optical paths having different lengths, coupling the divided optical signals to generate an sensing optical signal, outputting the generated sensing optical signal to the sensing optical fiber, dividing the sensing optical signal returning from the sensing optical fiber, progressing the divided sensing optical signals to the optical paths having different lengths, and coupling the divided sensing optical signals to generate an interference sensing optical signal.
