New research can give mobile devices that see through walls

Researchers at UT Dallas have designed a new imaging chip that in the future could let mobile devices see through walls, wood, plastics, paper and other objects. The research team have linked two existing scientific breakthroughs into one. The first involves looking at the terahertz range, a previously unused range in the electromagnetic spectrum. The second utilize advancements in new microchip technology.

Infrared wavelengths have been used for years, making night vision devices among other things possible. The terahertz band, one of the wavelength ranges that falls between microwave and infrared, has however up till now not been accessible for most consumer devices.

“We’ve created approaches that open a previously untapped portion of the electromagnetic spectrum for consumer use and life-saving medical applications”, said Dr. Kenneth O, professor of electrical engineering at UT Dallas and director of the Texas Analog Center of Excellence(TxACE). “The terahertz range is full of unlimited potential that could benefit us all.”
