Terahertz (THz) waves, whose frequencies range between microwave and infrared, are part
of the electromagnetic spectrum. A gap exists in THz literature because investigating THz …

Over the past few decades, significant attention has been paid to the biomedical
applications of terahertz (THz) technology. Nowadays, THz spectroscopy and imaging have …

Terahertz (THz) radiation is poised to have an essential role in many imaging applications,
from industrial inspections to medical diagnosis. However, commercialization is prevented …

The birth of terahertz imaging approximately coincides with the birth of the journal Optics
Express. The 20^ th anniversary of the journal is therefore an opportune moment to consider …

In this paper, a comprehensive set of techniques for quality control and authentication of
packaged integrated circuits (IC) using terahertz (THz) time-domain spectroscopy (TDS) is …

Noninvasive inspection of layered structures has remained a long-standing challenge for
time-resolved imaging techniques, where both resolution and contrast are compromised by …

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

Terahertz sparse deconvolution based on an iterative shrinkage algorithm is presented in
this study to characterize multilayered structures. With an upsampling approach, sparse …

During the real-aperture-scanning imaging process, terahertz (THz) images are often
plagued with the problem of low spatial resolution. Therefore, an accommodative super …

The process by which art paintings are produced typically involves the successive
applications of preparatory and paint layers to a canvas or other support; however, there is …
