Terahertz Imagery Progresses

ke4roh writes "Since Slashdot last discussed terahertz imaging, the European Space Agency's Star Tiger project has taken terahertz images of a human hand. Some of the pictures show just how useful the imagery might be for peering through walls and such - one of the images is through a 15mm pad of paper." The EE Times has another story.

Practical Application

Airport screening. This reminds me of the airport in Total Recall where Arnold had a gun. Very cool. 4th Amendment notwithstanding.

Thermal imaging

[Adam9]

Snip of some info from the tiger page:

Terahertz imaging can be achieved by observing the natural terahertz waves emitted by pretty much everything. Unlike light, terahertz waves are able to propagate through cloud and smoke providing a powerful advantage for certain remote sensing measurements. From a practical aspect they are also able to pass through windows, paper, clothing and in certain instances even walls.

Sounds like thermal imaging on steroids. Eventually, would this become the standard military surveillance method that could be used on a UAV in enemy or (god forbid) domestic airspace?

Good to see some constuctive devices being made

[Neophytus]

A device that can be used to see through walls has potential anti-terrorism uses, and if tweaked it could probably be used as a replacement for the mildly-dangerous xray technology. Also being able to be used for communications, this is a step in the right direction for research into radio technologys.

You'll want one of these then.
