Cellphones that can See through Walls and Detect Cancer

University of Texas at Dallas researchers have designed an imager chip that could one day turn mobile phones into devices that can see through walls, wood, plastics, paper and other objects.

The UT Dallas imager chip technology being explored by UT Dallas researchers is designed for imaging in the terahertz frequency range, specifically from 280 GHz (.28 THz) to about 1 THz. The terahertz frequency range is 1000 times higher than GHz (microwaves) and lower than near-infrared (which is just below visible light).
What makes this design a breakthrough is that it miniaturizes the imager, eliminating the need for a bulky, expensive lens system.
