Hyperbolic-Elliptical Lens Pairs for Fast THz-TDS Single-Pixel, Phase-Front Matched Imaging of Spherical Targets with an Extended Field of View

Abstract

Single-pixel reflection imaging of curved surfaces requires normal incidence and phase-front matching over a large FOV. Hyperbolic-Elliptical lenses were designed for a collocated THz-TDS setup to achieve imaging of samples such as the cornea in under 2 seconds.
