A compact double fiber Bragg gratings (FBGs) accelerometer based on an organic double-semicircle cantilever is proposed and experimentally demonstrated for low-frequency vibration measurement. The configuration is formed by two points of every FBG fixed at the two sides of the semicircle, efficiently avoiding the unwanted chirp effect of grating. The dynamic vibration measurements exhibit that the...
Polymer fiber Bragg gratings (FBGs) are made using the modified sagnac system with a 355nm pulsed laser from a photosensitive polymer optical fiber (POF) with external and core diameters of 290.6 and 21.0μm, respectively. Multimodes are reflected based on the reflection spectra of the gratings. The reflectivity spectra are also studied when such multimode polymer FBGs are subjected to axial static...
