Izdelava polarimetra in analiza prehoda svetlobe skozi dvolomno snov

Pirman, Jure (author), Žitko, Rok (mentor), Zupanič, Erik (comentor)

V prvem delu magistrske naloge je predstavljeno delovanje in izdelava polarimetra z vrtečo se $\lambda/4$-ploščico. Najprej je podan opis polarizacijskega stanja svetlobe z uporabo štirih Stokesovih parametrov.  Sledi teoretična obravnava delovanja  polarimetra z vrtečo se $\lambda/4$-ploščico ter predstavitev izdelave merilne naprave z opisom njene sestave in principom delovanja. Drugi del magistrske naloge je posvečen modeliranju in analizi prehoda svetlobe skozi optično vlakno, ki ohranja polarizacijo. Optično vlakno je obravnavano kot dvolomna snov z analitičnim modelom, ki upošteva poljuben spekter svetlobe. V nalogi opisani eksperiment služi kot test in prikaz zmožnosti natančne analize polarizacijskega stanja svetlobe med samim razvojem in kasnejšo optimizacijo polarimetra.

• Title: Construction of a polarimeter and analysis of transmission of light through a birefringent material

Abstract

The first part of this thesis presents the operation and construction of a polarimeter based on a rotating quarter waveplate. First, a description of light polarization is provided using four Stokes parameters. This is followed by a theoretical treatment of the operation of the polarimeter with a rotating quarter waveplate, along with the presentation of the construction of the measurement device, including a description of its composition and operating principle. The second part of the master's thesis is dedicated to the modeling and analysis of light propagation through a polarization-maintaining optical fiber. The optical fiber is treated as a birefringent material with an analytical model that considers arbitrary light spectra. The experiment described in the thesis serves as a test and demonstration of the capability for precise analysis of the polarization state of light during the development and subsequent optimization of the polarimeter.
