Terahertz systems

Updated February 2, 2010

New For February 2010!

"T-waves" are all over the news lately, it seems like they can perform all types of sensor magic. There are various definitions for what frequencies constitute "terahertz". Although "tera" implies 10^12, the casual definition of T-waves encompasses 300 GHz to 3 THz. Above 3 THz is considered the far edge of infrared spectrum.

One system application that has been fielded is for screening passengers at airports by seeing through clothing.

Recent articles have provided evidence that exposure to T-waves can "unzip" DNA molecules. We'll wait for more research on this before we offer our opinion(s).

It is possible to create an entirely passive sensor at terahertz frequency. However, passive (radiometric) sensors take much longer time to construct an image, and we don't want to wait any longer in security lines, do we?

More to come!
