Superman's X-Ray vision upgraded to T-Ray vision

... to exploit the unique advantages of terahertz (THz) radiation.
[relatively] unexplored [portion] of the electromagnetic spectrum
[this] elusive portion [lies] between infrared and microwave bands

... potential in biomedical imaging, genetics diagnostics, microelectronics,
and the chemical and biological materials identification fields.

... [T-ray] advantages [over] conventional imaging technologies.

Unlike X-rays, T-rays can be focused and are capable of producing images
with signature or fingerprint capability, also called functional imaging.

... the unique vibrational, rotational, and translational responses
of materials within the THz range provide information generally absent
in optical, X-ray and NMR images, enabling a sort of THz wave fingerprint
of the molecular structure of the material being imaged.

T-rays' low photon energy levels allow the imaging of biological tissue
without harmful ionizing radiation, making them safer than X-rays.

... ongoing research at the THz Center's four [laboratories:]
THz Optoelectronics lab,
THz Electronics lab,
THz Quantum Optics lab,
THz Spectroscopy lab.

... these researchers are overcoming significant challenges
posed by the lack of understanding of the fundamental physics
that underlie this large - and historically inaccessible -
portion of the electromagnetic spectrum.
