Imaging Reflectometry Measuring Thin Films Optical Properties
Běhounek, Tomáš ; Spousta, Jiří (oponent) ; Zicha,, Josef (oponent) ; Kotačka, Libor (oponent) ; Druckmüller, Miloslav (vedoucí práce)
An innovative method of evaluating thin film optical properties, the so called {\it Imaging Reflectometry} based on principles of spectroscopic reflectometry is presented in this thesis.\ Reflectance spectra of the film is extracted from intensity maps recorded by CCD camera, that correspond to chosen wavelengths, either over selected area or at one point.\ A theoretical model of reflectance is fitted to experimental data (the extracted reflectance spectra) by applying Levenberg~-~Marquardt algorithm in order to determine optical properties, their accuracy and reliability factor used to quantify a convergence successfulness of the reflectance model and hence the quality of the acquired results at given settings in a sense of a sensitivity analysis.
