Illumination intensity changes of side emitting optical fibers

Abstract

The main aim of this work is evaluation of side emitting plastic optical fibers (POF) illumination intensity changes in dependence on the distance from light source. Illumination intensity is measured along straight and bent fibers. The special devices for these measurements realization are described. The dependence of light intensity on the distance from light source for straight optical fibers is expressed by the exponential type model with two parameters, i.e. illumination intensity at the input into fiber and fiber attenuation factor. Preliminary results of measurement of light intensity in bent state are discussed. Influence of ratio between fiber diameter and bending cylinder diameter on the illumination intensity changes is presented.
