Abstract:Diplomsko delo govori o različnih vrstah spektralnih analizatorjih, njihovem delovanju. Poudarek je na optičnih spektralnih analizatorjih z uklonsko mrežico. Naš sistem temelji na takšnem spektralnem analizatorju. Opisane so komponente tega sistema, način sestave in na koncu umerjanje sistema. Sistem sestavljajo enorodovna optična vlakna, konkavne in konveksne leče, optični delilnik, prepustna uklonska mrežica, detektor in vir, ki je superluminiscenčna dioda. Predstavljeni so tudi eksperimentalni rezultati. Končen produkt je uspešno izdelan nizkocenovni optični spektralni analizator. Njegovo delovanje in umerjanje je predstavljeno s pomočjo optičnega senzorja raztezka, ki deluje na principu Fabry-Perot interferometra.

Title:LOW-COST OPTICAL SPECTRAL ANALYSER
Abstract:This diploma thesis presents different types of optical spectral analysers and their operation principles. The focus is on optical spectral analysers with a diffraction grating on which our system is based on. The thesis describes the mechanical alignment process and the calibration of spectral analyser. The system contains single mode optical fibers, concave and convex lenses, an optical coupler, a transmission diffraction grating, a detector and a light source which is a superluminescent diode. This diploma thesis also presents the experimental results. The final product is a successfully built low-cost optical spectral analyser. The properties of developed spectral analyser are experimentally evaluated by using optical fiber strain sensor based on an air-cavity Fabry-Perot interferometer.
Keywords:optical spectral analyser, diffraction grating diffraction grating, linear CCD, spectral analysis, Fabry-Perot
