Researchers from the Massachusetts Institute of Technology (MIT) have developed a prototype imaging system that’s able to read pages of a book without opening it.
A decade ago, a group at MIT demonstrated the ability to look through a sealed envelope using terahertz waves – the band of electromagnetic radiation between microwaves and infrared light. The project led Barmak Heshmat, a present-day research scientist at MIT’s Media Lab, to question just how deep one could look through a closed book using terahertz waves.
