Infrared challenges terahertz for industrial and security applications

SEPTEMBER 26, 2008--A near infrared (NIR) imaging technique has been developed that can be used for applications previously considered possible to image only by using terahertz (THz) waves.

SEPTEMBER 26, 2008--A near infrared (NIR) imaging technique has been developed that can be used for applications previously considered possible to image only by using terahertz (THz) waves. The technique developed at the University of Warwick uses NIR beams of light--around the wavelengths found in ordinary domestic remote controls--and signal recovery techniques commonly used in astronomy. This alternative technique can be realized using inexpensive electronics and is more portable and easier to use than THz imaging systems because no special power sources are required. Already successfully used in industrial environments and security applications, it can emulate the performance of commercial THz systems at a fraction of the cost and with much quicker image processing times.
