We report the development of RI POF sensors for water quality assessment using simple, fast and low-cost methods. The modification of the surface roughness of the POF's sensing region allowed to increase the sensor's sensitivity. The optical monitoring was performed through an intensity-based low-cost system comprising a LED, an optical coupler and two photodetectors. These sensors can be used for liquid refractive index sensing with 10-4 RIU resolution and future developments aim chemical and biochemical sensing using selective layers.

Abstract
We report the development of RI POF sensors for water quality assessment using simple, fast and low-cost methods. The modification of the surface roughness of the POF's sensing region allowed to increase the sensor's sensitivity. The optical monitoring was performed through an intensity-based low-cost system comprising a LED, an optical coupler and two photodetectors. These sensors can be used for liquid refractive index sensing with 10-4 RIU resolution and future developments aim chemical and biochemical sensing using selective layers.File in questo prodotto:
