A THz tomography imaging system

Imaging of internal contents of a multilayer material, organic tissue, or just structural properties of an object behind a barrier is commonly desired in many aspects of the medical field or industry. THz waves have the ability to penetrate into many materials and therefore enable the observation of the object's interior. In this paper, a 3D THz imaging system is presented, and a method for the tomographic imaging is described. The properties of the material layers can be determined through observation of amplitude and the phase of the reflected THz wave with the obtained images.
