Multiple FBG Wavelength Peaks Detection using Z-score algorithm

The functioning of fiber Bragg grating (FBG) sensors is primarily based on the monitoring of the Bragg wavelength shift. to accomplish this purpose, an expansion of algorithms had been proposed, from conventional most and centroid detection methods to more recently evolved correlation-primarily based techniques. We endorse a beneficial technique for finding FBG peaks based on the Z-rating algorithm. The Z-rating height Detection algorithm chooses the factors (peaks) which are outdoor the threshold the use of a transferring suggests and deviation. as it creates a separate transferring imply and deviation, the set of rules is relatively dependable and ensures that alerts do now not taint the brink. consequently, no matter the number of prior alerts, destiny alerts are detected with kind of the identical accuracy. The proposed method can be used successfully to discover more than one peaks whilst there are numerous cascaded FBGs and weak and noisy FBG signals.
