The present invention provides a method for measuring an optical sensor system comprising an array of intrinsic fiber optic sensors at an interrogator comprising an optical source and an optical detector. The method comprises the steps of emitting an optical signal to an array of intrinsic fiber optic sensors; detecting optical responses to the emitted signal from the sensors; associating each detected optical response with an individual sensor by determining within which region among a plurality of detection regions assigned to the individual sensors the optical response is detected wherein each detection region corresponds to a wavelength range in the bandwidth of the optical sensor system; and performing signal processing on each optical response to measure the value of the physical parameter detected by its associated sensor. A calibration of the detection region assigned to each sensor is performed at predetermined intervals.

System and method for interrogating an intrinsic fiber optic sensor

A system and method of determining the center of a peak of data points of an optical sensor are disclosed. The method can comprise the steps of performing an initial setup measurement of the sample points and extracting a peak; fitting the peak with a function that uses at least one of the peak's width, amplitude and center offset as fitting parameters; producing a set of linear equations which when solved calculate the optimum fit of a function to the peak assuming the previously calculated peak's width; and performing subsequent measurements of the data points to find peaks and solving the set of linear equations to determine the center of the peaks.
