Fluorescence based fiber-optic UV sensor

Abstract

© 2012 RAD Conference Proceedings. All rights reserved. In this paper a novel large-core fiber-optic UV sensor based on the principle of fluorescence is presented. Fiber-optic sensor with one end covered with mixture of powder from mercury lamp and index matching gel is fabricated. As a UV light source solar simulator in UV spectrum is used. Spectrum of the light on the other end of the optical fiber is measured by using USB spectrometer. The peaks of fluorescent emission in the visible spectrum of wavelengths are obtained at the output of the sensor with powder from mercury lamp.
