In this work is evaluated the performance of etched fiber Bragg gratings, assembled in
different configurations to operate as a refractometric sensor, in the analysis of water-ethanol …

Ethanol is a biofuel used worldwide. However, the presence of excessive water either during
the distillation process or by fraudulent adulteration is a major concern in the use of ethanol …

Evanescent field absorption spectroscopy in the infrared range of coiled fiber-optic sensor
has been applied to determine the low-level water content in ethanol. Principal component …

An intrinsic intensity modulated no core fiber sensor (NCFS) is presented in this paper for
rapid detection of adulteration in petrol with kerosene. The sensing principle is based on the …
