摘要：An object is to provide an inexpensive optical fiber sensing system capable ofperforming measurement at a higher accuracy by preventing influence of externaldisturbance other than a physical quantity of a measurement object, particularly, variationof polarization. An optical fiber sensing optical system according to the present inventionis configured to include a light source (5) which outputs search light having continuouswavelength components, a reflecting unit (71, 72, 73) which selects a portion ofwavelength components among the continuous wavelength components to generatedetection light, a wavelength discriminating unit (3) which the detection light is incident onand which generates transmitted light of which intensity is changed according to a changein wavelength thereof, a first light distributing unit (1) which irreversibly transmits thesearch light to the reflecting unit and transmits the detection light to an optical systemincluding the wavelength discriminating unit, a second light distributing unit (2) whichfurther divides the detection light transmitted from the first light distributing unit to theoptical system including the wavelength discriminating unit into light to the wavelengthdiscriminating unit and compensating light, and a delay unit (4) which generates a timedifference between time points of extraction of the compensating light and the
transmitted light to an outside.
