Abstract
A fiber optic sensing system. The fiber optic sensing system includes an optical source adapted to provide an optical signal at a plurality of wavelengths. The fiber optic sensing system also includes a plurality of wavelength taps for separating the optical signal into signal portions at each of the plurality of wavelengths. The fiber optic sensing system further includes a plurality of optical sensors, each of the optical sensors configured to receive one of the signal portions at a respective one of the plurality of wavelengths. The fiber optic sensing system still further includes a plurality of wavelength combiners for combining signal portions from the plurality of optical sensors into a recombined signal. Also included in the fiber optic sensing system is an optical receiver for receiving the recombined signal. The fiber optic sensing system also includes an optical fiber path between the optical source and the optical receiver.
