Terahertz 3D micro-tomography via time-resolved nonlinear ghost imaging

Abstract

Terahertz near-field microscopy represents a remarkable challenge, deeply limited by diffraction. With our technique; time-resolved nonlinear ghost-imaging, we demonstrate that spatio-temporal coupling affecting subwavelength measurements can be exploited as a lens, retrieving volumetric hyperspectral insights.
