Low-cost interrogation system for dynamic sensor applications using a resin based fiber Fabry Perot filter

In this paper it will be presented a prototype of low-cost power interrogator for dynamic sensor applications. The proposed system is based on the edge filter technique, where slope an in-house resin Fabry Perot (FP) used to actively narrowband laser centred at middle part FP region. composed source, circulator, photodetector, Arduino board and laptop. Tests have been performed in order check viability system. Finally, measurement pulse wave signal has by embedding 3D printed elastic membrane reading through interrogator.
