Route to Hyperspectral Terahertz Microscopy via Nonlinear Ghost-Imaging
Main list: Physics and Astronomy Colloquia
The Nonlinear Ghost Imaging is a novel imaging concept at the core of the Emergent Photonics Lab (EPic) ERC project “TIMING” proposed to overcome inherent limitations in the state of the art of terahertz imagers, in terms of resolution and imaging speed. Space-time coupling affects near-field time-domain imaging leading to fundamental systematic reconstruction issues. The seminar will present the methodological and technological route towards high-fidelity subwavelength imaging, establishing a rigorous framework to reconstruct hyperspectral images of complex samples inaccessible through standard fixed-time methods. It will also introduce the effort of EPic Lab in the investigation quasi-2D structure, enabling element in this research, based on exotic nonlinear field-matter interaction processes at dielectric surfaces.
