Tapered coated coreless optical fiber pollution sensor

View through CrossRef
Abstract This project is centered on the design and implementation of a pollution-sensitive optical fiber using a No core optical fiber. The sensors are used for estimating refractive indices and concentrations of various contaminated water (dirty pond water (contains mud and animal excrement), chemically contaminated water, oiled water, drainage water is an environmental pollutant, Sodium chloride water and sucrose water) and distilled water (The refractive index was measured in the laboratory with an Abbe refractometer device) as well as for evaluating the performance parameters such as sensitivity (11.11μm/RIU for tapered sensor 10min and 11.13μm/RIU for tapered sensor 20min) and resolution (0.000069 RIU for tapered No core 10min and 0.000079 RIU for 20min tapered) of sensor (multimode fiber-no core fiber-multimode fiber), with 40 nm thick gold (Au) metal film of the exposed sensing region).
