Read a book without turning pages

Terahertz imaging is making that happen. Using ultrashort bursts of terahertz radiation (between microwave and infrared) and an algorithm that can identify alpha-numeric characters and symbols, researchers at MIT and Georgia tech can now read through a stack of paper. It could also be done with X-rays but those are radioactive and rely on metals. The new system isn't and it can reflect from non-metallic inks.
This Device Can Read the Pages of a Book Without Opening It

This technique could have a lot of cool applications. Thoughts?

This will be great when it comes to old books too fragile to be opened. Sounds like it could be used to see if there is damage to an aircraft that can't be seen so maybe it can be used for to not only recover history but save lives.
