Abstract

The sensitivity of a fiber optical sensing assembly (2) with Fibre Bragg Gratings ( FBGs) (3, 4) to temperature variations in the associated light source (6) is reduced by using an interrogation system (1) with first and second sensors ( 12&15) that are connected to the sensing assembly (2) and to a reference element ( 14 ) to generate a measurement signal (M1, M2) and a reference signal, and a signal processing device (13), which identifies peaks (R1, R2) of the reference signal, compares a pattern of the identified peaks (R1, R2) with a known pattern of the reference spectrum to determine an order of wavelengths in the reference signal, and calculates for at least one peak an associated wavelength using the order of wavelengths in the reference signal, thereby avoiding that a different order of the peaks (R1, R2) in the reference signal, for instance due to temperature variations at the light source (6), results in false calculation of a wavelength in the measurement signal (M1, M2).
