Design and Implementation of a Terahertz (THz) Tomography System

Abstract

Tomography is an imaging technique that allows for the reconstruction of the internal structure of objects. Conventional magnetic resonance imaging (MRI) and X-ray computed tomography (CT) scans use tomography to create 3-D reconstructions of samples. Terahertz (THz) time domain spectroscopy (TDS), however, offers an alternative to MRI and CT due to its low-energy, non-ionizing radiation, and reasonable penetration lengths. This work presents an operational THz-TDS-based tomography setup, demonstrates its capabilities and explores some limitations. Theoretical background for the THz-TDS based tomography and possible explanations of the limitations are provided.
