We discuss in depth and clarify the problem of the analysis of data acquiring and processing in SPR fiber sensors, show how in many cases this analysis could and must be improved and propose a new method of SPR curve shaping, apt for sensors encapsulated or inaccesible. We illustrate the use of the method with real experimental examples.engjournal articlehttps://doi.org/10.1016/j.snb.2018.04.083https://www.sciencedirect.com/science/article/pii/S0925400518307871restricted access621.391.6531.14535Optical fiberSurface Plasmon ResonanceFiber-optic sensorsSignal processingElectromagnetismoÓptica (Física)2202 Electromagnetismo2209.19 Óptica Física
