Abstract :
Three dimensional (3D) terahertz (THz) imaging or THz tomography has recently proven to be useful for non-destructive testing of industrial materials and structures. In place of previous imaging techniques such as THz pulse radar, we propose a THz optical coherence tomography (OCT) using two kinds of THz sources such as incoherent noise and frequency-swept sources, and demonstrate 3D imaging in the frequency regions from 300 GHz to 800 GHz.
