title = "Hyperbolic-elliptical lenses for rapid THz reflection imaging of curved biological surfaces",
abstract = "We describe a novel approach for designing a hyperbolic-elliptical lens pair system and associated normal-incidence beam steering for rapid single-pixel THz-TDS imaging of curved surfaces with a large field-of-view (FOV). The lenses are optimized in an iterative algorithm to ensure phase-front matching to spherical surfaces such as the human cornea. The lenses were fabricated using HDPE and their optical performance was characterized. The new lenses provide a FOV which is 12\% larger than previous methods using off-axis parabolic mirrors, while the beam steering approach reduces scanning time from several minutes to about 4 seconds or less. The scanner developed in this work will enable in vivo imaging of corneas in clinical settings.",
