Doctoral Thesis / Dissertation from the year 2023 in the subject Physics – Optics, , language: English, abstract: The present book is an extended version of my doctoral work on polarization optics and digital holography, which depicts the preliminary concepts of polarization optics and deals with their some novel applications in digital holography and computational imaging.
First, it’s about basic concepts and development of polarization-sensitive imaging techniques, advancing the existing polarization-sensitive interferometry and digital holographic (DH) techniques. Secondly, the techniques have been applied for the polarimetric characterization of anisotropic samples. In particular, aforesaid polarimetric investigations are mainly focused on the LC cells and SLMs. Further, some crucial issues in computational imaging, for instance, limited depth of field (DOF), and axial intensity of diffraction-limited imaging systems under low light throughput have been examined thoroughly. Attempts have been put forward to address the imaging artifacts using the concept of polarization coded apertures (PCAs), which are experimentally demonstrated using the polarization modulation characteristics of LC-SLM.
The goal of this book is to disseminate its contribution to wider researcher fraternity. It is expected that this book will serve as a preliminary guide for undergraduate and postgraduate students, research scholars who are interested to pursue their research in polarization optics and holography domain.
