Abstract:V okviru doktorske disertacije smo razvili in izdelali optični senzor lomnega količnika, optični senzor merjenja temperature ter optično kvazi porazdeljeno omrežje na osnovi standardnega mnogorodovnega telekomunikacijskega optičnega vlakna z gradientnim lomnim likom za merjenje lomnega količnika in temperature. Poseben poudarek smo namenili medsebojnim odvisnostim med posameznimi parametri. Raziskali smo njihov vpliv na izgube, medsebojne vplive ter modulacijsko globino posameznih senzorjev v omrežju. Na podlagi temeljite analize vplivov posameznih parametrov na delovanje omrežja smo izdelali model, ki omogoča načrtovanje in izdelavo optičnih omrežij sestavljenih iz evanescentnih senzorjev z omejenimi medsebojnimi vplivi med posameznimi senzorji. Model smo preizkusili s praktično izdelavo in evaluacijo dveh omrežij, ki sta temeljila na predhodno izdelanih točkovnih senzorjih; omrežjem za merjenje lomnega količnika in omrežjem za merjenje temperature.

Title:Sensor network for measurements of refractive index and temperature based on gradient multimode optical fibers
Abstract:We have designed and developed an optical refractive index sensor, optical temperature sensor and optical quasi distributed network based on standard multimode telecommunication graded index fiber for measurements of refractive index and temperature. Special attention was given to inter – dependence of different parameters and their influence on losses, cross talk and modulation depth of individual sensors in the network. Based on the thorough analysis of all the influential parameters on the behavior of the network, a model that enables design and development of optical networks based on optical evanescent sensors with decreased cross talk could be derived. The model was evaluated with a practical design of two quasi distributed sensor networks that were constructed of previously designed single point sensors. One network was constructed for measurements of refractive index while the other enabled measurements of temperature.
Keywords:Temperature sensor, refractive index sensor, optical fibers, quasi distributed network, optical fiber losses, sensor inter-dependencies
