Mail engineering does not need to open the envelope

A team of scientists in Italy and the Netherlands has successfully developed a new technology that can penetrate thin layers of materials, promising a breakthrough for nanotechnology, medical imaging and cockroach operations. message.

The technique is based on the use of laser beams and a decoded computer. It has been successfully tested when applied to observing objects placed behind the frosted glass that the naked eye can not see clearly.

Initially, the team used a laser beam on the translucent glass. (The light will scatter, making the object behind the glass obscured). Then diffused light rays are placed on the computer to analyze and reproduce the image of the object behind the glass.

The results show that light is scattered.

With this technique, scientists hope it will help much for non-invasive scanning technology in medicine and nanotechnology, such as seeing the inside of a computer chip without the need. must open it.

Even new techniques are useful for spying. "In principle, you can read a letter even though the letter is sealed in an envelope, which is useful if you are a spy," says Allard Mosk of the Institute of Nanotechnology at the University of Twente. Said the study's co-author.

Although a partial overhaul of current penetrating technology has been overcome, the new technology has limitations. It still can not see the material hidden under the black material and also not really useful for the work of peeping. Because when laser light is easy to detect.
