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 a low-cost power interrogator for dynamic sensor applications. The proposed system is based on the edge filter technique, where the slope of an in-house resin based Fabry Perot (FP) filter is used to actively filter the power of a narrowband laser ce...
