摘要：
This paper presents theoretical analysis of impulsive strain processing by fiber Bragg Grating (FBG) with linearly changeable period. Tensile and compression excitations acting along the longitudinal fiber axis are studied. The prepared calculation is based on the piecewise-uniform period assumption for chirped grating. Then the obtained reflected spectrum is analyzed by calculating its centroid frequency. This allows it to calculate rise time error as a function of length of distortion leading edge and grating length which allows it to establish influence of grating length on processing accuracy.
