Terahertz Scanners Are Coming To A Smartphone Near You

Your smartphone could have a new feature on it soon, thanks to a team in Texas. If you thought X-Ray glasses were just for the science fiction magazines and Johnson Smith Company you may be proven wrong soon. Some basic wrangling with transistors in a smartphone can change it from just a regular photo snapper into a device that can see through walls.

This is not on the level of "fake vomit" and "hand buzzers" we are talking about here. This is something on the level of the current "miracle" of the "retina screen" and GPS. The breakthrough came from a change in how science thinks about a common every day transistor, the CMOS transistor. With that transistor and something called a "Schottky Diode", the frequency level of detection gets very high. It goes into the terahertz range. At that range it is nearly at the frequency of light. Red light has a frequency of 460 terahertz. A smartphone that can detect this range of frequency from a distance is actually not that hard to make, since they are already using CMOS transistors. All that is needed is to add the diode.

A doctor on the Texas team stated that the combination of CMOS and terahertz capability would mean special devices could be attached to the back of a smartphone. The camera is already installed on most smartphones, but the special chip and receiver could be installed near it. The doctor and his group plan on making such a device, but they want to limit the distance it can "see" to four inches. It is for sure that the general population is going to want more range than that.

Other terahertz imagers have been made in the past, but they were large and required more than one lens to do their job. This development by the scientists from Texas changes all that. The electromagnetic signal coming from a smartphone with a terahertz sender and receiver will send a signal to places where light can not go. It will be able to read what is reflected, similar to radar. The good doctor on the Texas team mentions using their invention for "life saving medical" applications. He also mentions that it could be used for "all kinds of things" that have not been thought up yet. The key will be the new microchip technology inside the upcoming smartphones. Expect this to be coming to smartphones in the near future, as the technology is ready now.
