THz Wave 3D Imaging and Tomography
THz waves are transparent to most of the dry dielectric materials. This property makes THz wave a promising candidate for nondestructive evaluation of the internal structures of targets. THz wave time-of-flight imaging method is one of the techniques to extract the information about the layered structures of a target. If there is no layer structure within the target, or if the interesting features are not located on those layer structures, one needs to use tomographic imaging techniques to extract those interesting information .
