Abstract
The dual-wavelength interrogation of interferometric fiber-optic sensors is discussed. This approach can be used to alleviate the intrinsic ambiguity associated with the cosinusoidal output of interferometric systems. The application of this technique in temperature sensing and its use in the all-fiber gyroscope is reported.Keywords
