Researchers have devised a way to read books when they’re closed. No, you didn’t read it wrong. Researchers from MIT and Georgia Tech are designing an imaging system that can read closed books.
A paper published Friday in the journal Nature Communications describes a prototype for this ingenious system that correctly identified the letters on the top nine sheets of a stack in which each sheet had one letter printed on it.
“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,” Barmak Heshmat, co-author of the paper and a research scientist at the MIT Media Lab, said in a statement. He added that the new system can analyze materials organized in thin layers.
The system uses terahertz radiation, which unlike X-Rays, can distinguish between ink and paper. It also gives better depth resolution when compared to ultrasound. Paper and ink bend light at a different degree, which helps the system in distinguishing between them. The 20-micron deep air pockets between the pages help the system differentiate between the pages of a book… see more
