Abstract

This thesis explores the advancements and applications of Fourier domain Mueller matrix polarimetry in the study of polarization properties of light and materials. The Mueller matrix provides a comprehensive description of polarimetric phenomena and enables the extraction of valuable information about material qualities and optical anisotropy. However, traditional real-plane imaging techniques have limitations, such as determining mean values along a direction and susceptibility to noise and disturbances. Fourier polarimetry imaging is implemented to overcome these limitations, leveraging the robustness and comprehensive nature of Fourier optics. Fourier domain polarimetry offers a powerful approach for characterizing the polarimetric properties of samples, providing insights into spatial correlations within inhomogeneous optical media. By analyzing the Fourier domain polarimetry data using Fourier inverse analysis, valuable information about structural and compositional features can be extracted, enabling enhanced control and manipulation of light-matter interactions. The thesis highlights the significance of Fourier domain polarimetry and Fourier inverse analysis in uncovering the behavior of light at microscopic and nanoscopic scales. The techniques are particularly effective in identifying and characterizing waveguide mode excitations in nano-optical systems, contributing to the design and optimization of nanophotonic devices and systems. Fourier domain Mueller matrix polarimetry offers a comprehensive understanding of the polarization properties of light and materials, with applications in diverse areas such as remote sensing, biomedical imaging, and material science. The techniques presented in this thesis provide valuable insights into the inherent optical properties of micro and nano-optical systems, facilitating the development of advanced optical devices, sensors, and technologies in materials science, biophotonics, and nanotechnology.
