Terahertz security vision system in pandemic environment

We developed a testbed that helped to measure the transmission of different means of individual protection in the 2mm wavelength range, reflection of THz waves by human skin and absorption of THz waves by exhalted air. Using this testbed we managed to recover the relief of human face hidden behind t...

Description
Summary:We developed a testbed that helped to measure the transmission of different means of individual protection in the 2mm wavelength range, reflection of THz waves by human skin and absorption of THz waves by exhalted air. Using this testbed we managed to recover the relief of human face hidden behind the opaque materials.
