Terahertz detection and carbon nanotubes

Terahertz detection and carbon nanotubes

Researchers at Sandia National Laboratories, along with collaborators from Rice University and the Tokyo Institute of Technology, are developing new terahertz detectors based on carbon nanotubes that could lead to significant improvements in medical imaging, airport passenger screening, food inspection and other applications. Here, Sandia researcher François Léonard discusses the work.

The Terahertz Imager T-SENSE ® visualizes enclosed hazardous substances precisely in letters as well as small parcels safely and effectively.

The process is safe, fast and without risk to the health of the user. Unlike conventional visualizing processes such as x-ray technology, the T-SENSE ® functions on the lower Terahertz frequency level with safe millimeter waves that enable non-transparent materials to be illuminated.

The T-SENSE ® rapidly visualizes the objects to be examined and makes potentially dangerous contents visible. Since the device is highly sensitive, it even recognizes powders and adhesives.

Simple and intuitive application permits the device to be used with easy instructions. The scanning procedure shows a picture that is checked and analyzed by the user. The T-SENSE ® can be used anywhere, from the office to large postal centers. In combination with the T-COGNITION ® , the material recognized in the suspicious item can also be identified.

  1. It will be evil surveillance states that use this system to search people.  Of course they will invoke the terrorist boogyman they created, fund, and train.

  2. For active systems thz waves have been found to unzip DNA at power levels measuring in microwatts due to resonance.

  3. Very cool. Looking forward to the medical applications. I imagine it would be many times more expensive than a standard MRI machine however.
