As the volume of composite parts continues to rise, quality and performance specifications
are becoming more and more demanding. In this context, robust and reliable nondestructive …

Terahertz (THz)-band (0.1~ 10 THz) communications are celebrated to be a crucial enabling
technology for sixth generation (6G) wireless systems that fulfil the stringent requirements of …

Spatial resolution, spectral contrast and occlusion are three major bottlenecks for non-
invasive inspection of complex samples with current imaging technologies. We exploit the …

Terahertz (THz) technology has firmly established itself as an effective sensing and
nondestructive testing (NDT) technique for the detection of substances and physicochemical …

3D terahertz computed tomography has been performed using a monochromatic millimeter

Three-dimensional terahertz computed tomography has been used to investigate dried
human bones such as a lumbar vertebra, a coxal bone, and a skull, with a direct comparison …

Wavelet transform is an important tool in the computational signal processing of terahertz
time-domain spectroscopy (THz-TDS) measurements. Despite its prevalence, the effects of …

In this paper, a model of the beam propagation is developed according to the physical
properties of THz waves used in THz computed tomography (CT) scan imaging. This model …

In this paper, we present an advanced image processing sequence to perform
nondestructive inspection from 3-D terahertz (THz) images. We develop all the steps starting …

We present for the first time a system and new algorithms for spectral THz-tomography. The
electric field of single cycle ultra short THz-pulses can be measured time resolved in …
