Abstract
This paper reports the real-time linear-in-distance sampling for a resonance frequency mapping system based on an identical weak fiber Bragg grating (FBG) array. Based on a function of an external clock for the sampling timing of uniform distance spacing, 100 identical weak FBGs could be interrogatedexamined with a high linearity of 0.9996 (R2).
