A group of researchers from MIT and Georgia Tech have built a device that can see through paper and distinguish ink from blank paper to determine what is written on the sheets. The prototype successfully identified letters printed on the top nine sheets of a stack of paper, and eventually the researchers hope to develop a system that can read closed books that have actual covers.
“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 the MIT Media Lab and author on the new paper, published today in Nature Communications.
