T-ray tomographic imaging

Summary form only given. We present three terahertz wave (T-ray) tomographic imaging modalities: T-ray computed tomography (T-ray CT), T-ray diffractive tomography (T-ray DT), and tomographic imaging with a Fresnel binary lens. T-ray CT provides 3-dimensional (3D) images and reveals information about the target for functional imaging. T-ray DT achieves sub-mm spatial resolution, and a binary lens leads a novel imaging modality with the use of a broadband T-ray pulse.
