Work continues on a chip that will allow smartphones to see through objects using signals in the 200GHz to 400GHz range.
Imagine having a phone that gives you the ability to look through walls. According to IEEE Xplore (via CBS News), a project that has been in the works for 15 years continues progressing. The goal is to develop a chip that allows smartphone users to see through solid surfaces similar to X-rays. But the latter is harmful to humans so instead of actually using X-rays, the phone uses signals in the 200 GHz to 400 GHz range.
So far, tests have shown that the technology can see through dust, dense fog, and airborne particles that light normally won’t penetrate. In a more recent test, researchers were able to look through a cardboard sheet. Before we get too excited about this, the report notes that it could be only a few years before smartphone users will be able to see through walls and objects using gigahertz signals.
