【on.cc 東方互動專訊】美國德州大學研究人員設計出一種晶片，可讓智能手機擁有漫畫書中「超人」擁有令人妒忌的能力：看穿牆壁、衣服或其他物件，應用範圍廣泛。

這種晶片的設計原理是利用能穿透日常生活物件的太赫磁(THz)電磁波進行掃描探測，令手機具備透視能力。THz的波長介乎手機訊號微波和夜視鏡紅外線之間。

因為私隱問題，研究人員只研發探測距離少過4吋的透視圖像晶片。

The REAL X-Ray spex: New 'terahertz' scanner lets mobile phones see through walls - and through clothes

[size=1.4em]Scanner uses 'terahertz' spectrum - between infrared and microwaves
[size=1.4em]Can see through walls, wood and plastics
[size=1.4em]Doctors could use small, cheap devices to see tumours inside body

[size=1.2em]Comic-book superpowers could become reality as scientists have designed a phone that works as 'X-Ray spex'.
[size=1.2em]A hi-tech chip allows a phone to 'see through' walls, wood and plastics - and (although the researchers are coy about this) through fabrics such as clothing.

[size=1.2em]Doctors could also use the imagers to look inside the body for cancer tumours without damaging X-Rays or large, expensive MRI scanners.

Close up of a CMOS chip - a new version of the commonly used chips would allow users to capture images 'through' walls and even inside the human body

[size=1.2em]The researchers claim it could allow DIYers to detect studs within walls, or allow businesses to detect counterfeit money.
[size=1.2em]At present, it's designed to work over a short range - and works with a normal-sized microchip that could fit into phones or other handheld electronics.

[size=1.2em]The team's research involves tapping into an unused range in the electromagnetic spectrum.
[size=1.2em]But the terahertz band of the electromagnetic spectrum, one of the wavelength ranges that falls between microwave and infrared, has not been accessible for most consumer devices.
[size=1.2em]‘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.

[size=1.2em]‘The terahertz range is full of unlimited potential that could benefit us all.’

[size=1.2em]Using the new approach, images can be created with signals operating in the terahertz (THz) range without having to use several lenses inside a device. This could reduce overall size and cost.

[size=1.2em]The second advance that makes the findings applicable for consumer devices is the technology used to create the microchip.

[size=1.2em]Chips manufactured using CMOS (Complementary Metal-Oxide Semiconductor) technology form the basis of many consumer electronic devices used in daily life such as personal computers, smart phones, high definition TV and game consoles.
[size=1.2em]‘CMOS is affordable and can be used to make lots of chips,’ Dr. O said. ‘The combination of CMOS and terahertz means you could put this chip and receiver on the back of a cellphone, turning it into a device carried in your pocket that can see through objects.’
[size=1.2em]Due to privacy concerns, Dr. O and his team are focused on uses in the distance range of less than four inches.
[size=1.2em]Consumer applications of such technology could range from finding studs in walls to authentication of important documents. Businesses could use it to detect counterfeit money.

[size=1.2em]Manufacturing companies could apply it to process control.

[size=1.2em]There are also more communication channels available in terahertz than the range currently used for wireless communication, so information could be more rapidly shared at this frequency.
[size=1.2em]Terahertz can also be used for imaging to detect cancer tumors, diagnosing disease through breath analysis, and monitoring air toxicity.

[size=1.2em]‘There are all kinds of things you could be able to do that we just haven't yet thought about,’ said Dr. O, holder of the Texas Instruments Distinguished Chair.

[size=1.2em]The research was presented at the most recent International Solid-State Circuits Conference (ISSCC). The team will work next to build an entire working imaging system based on the CMOS terahertz system.
