A comparative study is presented between Bragg grating (FBG) and polarimetric sensors (PS), two of the most promising fiber\noptic sensing techniques for the structural health monitoring of smart materials based on carbon fiber composites. The paper\ndescribes the realization of a test plate equippedwith both types of sensors and reports the characterization under static and dynamic\nconditions, highlighting pros and cons of both technologies. The FBG setup achieves 1.15 �± 0.0016 pm/kg static load response and\nreproduces dynamic excitation with 0.1% frequency uncertainty; the PS system exhibits a sensitivity of 1.74 �± 0.001mV/kg and\nreproduces dynamic excitation with 0.5% frequency uncertainty. It is shown that the PS technology is a good and cheap alternative\nto FBG for vibration-monitoring of small structures at high frequency.
