摘要
The invention relates to a method of interrogating a multiple number of optic sensors. The method comprises the steps of providing a multiple number of optic sensors included in a single optic path and having spectrally separated resonance spectra, and providing a single interrogation unit coupled to the single optic paths. Further, the method comprises the steps of selecting a limited number of interrogation wavelengths for each optic sensor and programming a programmable laser source, included in the single interrogation unit, in a sequence of the selected interrogation wavelengths. In addition, the method comprises the steps of interrogating the optic sensors by operating the laser source in the sequence of the selected interrogation wavelengths, and performing measurements on the programmable laser source output for correcting the interrogating step.
