Title: "The geometry hidden in light"

Time/Location: Friday February 3rd, 2023 at 15:00 in Aula 0M01 - Department of Physics - Federico II 

Abstract

In this talk I'll discuss several geometrical representations in various optical phenomena and their applications. Such geometry is often not evident but hidden in abstract spaces that describe the many degrees of freedom of light. Among the topics discussed are the description of various types of optical beams and their properties, polarization of paraxial beams and focused fields, as well as the concept of geometric phase and its multiple incarnations in optics. Finally, a series of applications will be presented, including new techniques for measuring nanostructures based on analogies with quantum formalism, microscopic position detection and 3D orientation of fluorophores, new forms of displacement interferometry, as well as simple formulas to understand the effects of some deficiencies in imaging systems.
