Paper Abstract

Sensitivity of the refractometric sensors on the base of three-layer lightguides was examined in this paper. Characteristic equations for calculation of propagation constant of lightguides with rectangular and circular cross section are used for the determination of influence surfacing films parameters on transducers sensitivity. Experimental investigations confirmed the possibility of transducers sensitivity increase with intensity modulation when using thin surfacing films. Moreover, such structure of sensitive element allows to control the sensitivity of changing wavelength of the light source.
