Wb. Lin et al., The effects of polarization of the incident light-modeling and analysis ofa SPR multimode optical fiber sensor, SENS ACTU-A, 84(3), 2000, pp. 198-204
A 3D skew ray modeling has been developed to consistently explain the exper
imental phenomena for an intrinsic SPR multimode optical fiber sensor. The
effects of the polarization direction of the incident light at certain cond
itions have been clarified. This simulation is needed to accurately detect
the variations of the refractive index of the bulk medium and of the thickn
ess of the thin surface layer. More complete knowledge about light energy t
ransmission by the skew ray in the multimode step-index fiber is obtained b
y this investigation. (C) 2000 Elsevier Science S.A. All rights reserved.
