Judging a book through its cover
Judging a book through its cover. Larry Hardesty. MIT News Office. September 9, 2016.
MIT researchers and colleagues are designing an imaging system that can read closed books, and particularly antique books that are too fragile to touch. The system uses terahertz radiation emitted in short bursts that can gauge the distance to individual pages of the book and can distinguish between ink and blank paper, in a way that X-rays can’t. It is still a new technology but they are working to improve the depth of penetration of a book and also the accuracy.
