In this work, we propose a signal processing algorithm to enlarge the refractive index dynamic range (RIDR) of the Fresnel reflection-based fiber Fabry–Perot (FR-FFP) sensors. In this approach, t…
The reflectance of a hybrid fiber Fabry-Perot interferometer modulated by the Fresnel reflection at the fiber tip was used to assess the refractive index (RI) of liquid samples. Notwithstanding the…
