Terahertz imaging makes it possible to acquire images of objects concealed underneath
clothing by measuring the radiometric temperatures of different objects on a human subject …

We describe the construction and performance of a passive, real-time terahertz camera
based on a modular, 64-element linear array of cryogenic hotspot microbolometers. A …

This paper gives an overview of measurement techniques used in the THz region of the
electromagnetic spectrum, from about 100 GHz to several THz. Currently available …

The achievable instrument sensitivity is a critical parameter for the continued development of
terahertz (THz) applications. Techniques such as cavity-enhanced techniques and cavity …

Aiming at the requirement of passive terahertz imaging, we report a high-sensitivity terahertz
detector based on an antenna-coupled AlGaN/GaN high-electron-mobility transistor (HEMT) …

A cryogenic bolometer has been fabricated using a bundle of single-walled carbon
nanotubes as absorber. A bolometric response was observed when the device was exposed …

This paper reports the design (electrical, mechanical, and thermal), fabrication technology
by postcomplementary metal-oxide-semiconductor (CMOS) nanomachining, and …

We demonstrate a frequency-selective energy-harvesting sub-THz superconducting
bolometer. The bolometer, a two-dimensional array of connected metamaterial resonators …

The inherent restrictions of human body images acquired at visible spectrum hinder the
performance of person recognition systems built using that kind of information (eg scene …

Frequency Selective Surfaces (FSS) are periodic array of sub-wavelength antenna
elements. They allow the absorptance and reflectance of a surface to be engineered with …
