ABSTRACT:
A fiber optic sensor comprises a first optical signal source that produces an optical signal of wavelength .lambda..sub.1 and a second optical signal source that produces an optical signal of wavelength .lambda..sub.2. A first WDM coupler is connected to the first and second optical signal sources to combine signals output therefrom. An optical fiber is connected to the WDM coupler to guide the combined optical signals therefrom. A second WDM coupler is connected to the optical fiber to separate the optical signals of wavelength .lambda..sub.1 and .lambda..sub.2. A fiber optic sensor array containing a plurality of fiber optic sensors is connected to the second WDM coupler and arranged such that optical signals of the wavelengths .lambda..sub.1 and .lambda..sub.2 are directed to different fiber optic sensors in the fiber optic sensor array. A third WDM coupler is arranged for combining signals of wavelength .lambda..sub.1 and .lambda..sub.2 output from the fiber optic sensor array. FDM multiplexing apparatus is connected to the third WDM coupler apparatus, Demultiplexing and demodulating apparatus is connected to the FDM multiplexing apparatus for producing output signals corresponding to the fiber optic sensors.
