The ultimate goal in all fiber optic systems is to extract information about the mechanical perturbations. For example, this information may be the frequency dependent index of perturbation. For security systems we desire to detect and differentiate between different intruders based on the mechanical response. In this article classification architecture is developed. Emphasis is placed on the problem of feature extraction to reduce all spectral responses to several features allowing simple classification of different perturbation. The identification of specific intruder signals was investigated in the following application settings: interferometer Sagnac-Sagnac fiber optic sensor responses, interferometer Michelson-Sagnac fiber optic sensor responses, modalmetric fiber optic sensor responses. The field of signal processing techniques for fiber optic systems is relatively unexplored; however work has been reported in determining optimal techniques for demodulation, denoising, localization place of perturbance and identification kind of perturbation for specific, different fiber optic systems.
