How Future Cellphones Will Be Able To See Through Walls
Researchers at UT Dallas have designed an imager chip that allows mobile phones to see through structures and objects.
It appears our favorite comic book superhero’s X-ray vision may become a reality we will be able to experience for ourselves, thanks to two scientific advances made by researchers at University of Texas at Dallas. One involves tapping into an unused range in the electromagnetic spectrum, while the other is new microchip technology. Typically the electromagnetic spectrum corresponds to wavelengths of energy, whether they be in the form of AM/FM radio signals, microwaves, or infrared for night vision. With a new approach, the researchers learned that terahertz (a wavelength falling between microwave and infrared in the electromagnetic spectrum) could produce images created with signals without having to use several lenses inside a device.
