Metoda merenja talasne dužine monohromatske svetlosti primenom spektralno osetljivih optičkih komponenti / Method of measuring monochromatic light wavelength by using wavelengthsensitiveoptical components

Description

<p>U ovoj doktorskoj disertaciji dat je predlog nove metode za merenje talasne dužine monohromatske svetlosti pomoću spektralno osetljivih optičkih komponenti. Princip rada predložene metode se zasniva na kombinovanju spektralnih osetljivosti fiber-optičke račve i dva različita fotodetektora.<br />Izvršena je implementacija i karakterizacija senzorskog sistema za merenje talasne dužine monohromatske svetlosti. U eksperimentalnoj postavci korišćena je 2&times;2 fiber-optička račva, germanijumska (Ge) fotodioda i indijum-galijum-arsenid (InGaAs) fotodioda. Postignuta je linearnost sa faktorom korelacije R2=0.99942 i merna rezolucija od 17 pm u opsegu talasnih dužina svetlosti od 1575 do 1615 nm (L-opseg). U istom opsegu, dobijena je merna greška od približno &plusmn;0.2 nm i ponovljivost od &plusmn;0.16 nm. Ispitani su uticaji promena temperature, snage optičkog izvora i šuma na karakteristike senzorskog sistema.</p> / <p>In this thesis, a new method for measurement of monohromatic light<br />wavelength by using wavelength-dependent optical components is proposed.<br />The principle of operation of the proposed method is based on combining<br />spectral sensitivities of fiber-optic coupler and two different photodetectors.<br />Sensor system for measurement of monochromatic light wavelength is<br />implemented and characterized. Experimental setup consists of 2&times;2 fiberoptic<br />coupler, germanium (Ge) photodiode and indium-gallium-arsenide<br />(InGaAs) photodiode. Excellent linearity (R2=0.99942) and measurement<br />resolution of 17 pm are achieved in measurement range 1575-1615 nm (Lband).<br />In the same measurement range, measurement error of approximately<br />&plusmn;0.2 nm and repeatibility of &plusmn;0.16 nm are obtained. The influence of<br />temperature, optical source power and noise on sensor system characteristics<br />is investigated.</p>
