This lets extremely fine distinctions be made, such as whether a reflected image comes from one page or the next one a fraction of a millimeter down.The result is terahertz femtophotography, and the researchers were able to make it determine the distance to the first 20 pages of a book, and it could pick out individual letters printed on the first 9.
