Abstract :
Terahertz (THz) tomography is a recent imaging technique allowing 3D inspection of opaque objects. In this paper, we investigate a dual-energy experimental setup and a THz tomographic reconstruction algorithm based on dual-energy measurements. We discuss how this dual-energy approach is able to extract physical properties of acquired samples in addition to the 3D reconstruction from acquisitions measured with a 84/287GHz transmission scanner.
