Abstract

Peak-detection algorithm is a crucial part of fiber grating signal demodulation. It plays a decisive role in the accuracy, speed and anti-noise performance of the entire system. This article introduces the research focusing on peak-detection algorithms and summarizes the common peak-detection algorithms in recent years into three types: traditional direct peak-detection algorithms, classic fitting peak-detection algorithms, and innovative improved algorithms. It mainly includes direct peak-detection algorithm, centroid detection algorithm, polynomial fitting method, gauss fitting algorithm, cubic spline interpolation algorithm, adaptive semi-peak-seek algorithm and Steger peak detection algorithm. The principles of various peak-finding algorithms are explained and the characteristics and performance of each algorithm are comprehensively compared. It is convenient to choose the optimal demodulation algorithm in the future research tasks according to different actual conditions and requirements.
