Abstract
The application of the processing technique based on straightforward detection of output spectrum of sensing interferometer for simultaneous measurement of temperature and strain is demonstrated. The processing algorithm includes the construction of an analytical signal from a nearly periodic part of the output signal in the spectral domain, and further analysis of its phase. The parameters of spectrometer, visibility, and signal-to-noise ratio of interference pattern also as the spectral bandwidth of the light source were optimized to provide the desired accuracy of temperature and strain definition and low level of cross-sensitivity.
