A team of Scientists, including one of Indian origin, have developed a new technology that can read pages of a closed book, an advance that may help archaeologists look into antique books without touching them.

Ramesh Raskar, an Indian researcher from Massachusetts Institute of Technology (MIT) in the US, tested a prototype of the system on a stack of papers, each with one letter printed on it. The system was able to correctly identify the letters on the top nine sheets.

“The Metropolitan Museum in New York showed a lot of interest in this, because they want to, for example, look into some antique books that they don’t even want to touch,” said Barmak Heshmat, a research scientist at MIT.

This technology uses terahertz radiation, the band of electromagnetic radiation between microwaves and infrared light; it has several advantages over other types of waves that can penetrate surfaces, such as X­rays or sound waves.

The Terahertz frequency profiles can distinguish between ink and blank paper, in a way that X- rays cannot, and has much better depth resolution than ultrasound. The system exploits the fact that between the pages of a book tiny air pockets are trapped about 20 micrometers deep.

This technology relatively the latest yet young to use, but continuous efforts are been made to make it’s more efficient to work for professional uses. This new innovative story was published in The Journal Nature Communications.
