A THz Tomography System for Arbitrarily Shaped Samples

Journal of Infrared, Millimeter, and Terahertz Waves volume 38, pages 1179–1182 (2017)Cite this article

Abstract

We combine a THz time-domain spectroscopy system with a robotic arm. With this scheme, the THz emitter and receiver can be positioned perpendicular and at defined distance to the sample surface. Our system allows the acquisition of reflection THz tomographic images of samples with an arbitrarily shaped surface.
