MIT's handheld FAR-NDT device sees cracks in structures

Darren Murph

We've already seen radars come in handy when dodging impending attacks and avoiding accidents, but researchers at MIT are utilizing the technology to make sure our roadways and structures aren't pushed beyond their limits. A newfangled handheld device uses FAR-NDT (far-field airborne radar nondestructive testing) in order to "see through the fiberglass-polymer wrapping often used to strengthen aging concrete columns to detect damage behind the wrapping not visible to the naked eye." Furthermore, the technique can be executed from about 30 feet away and "requires no dismantling or obstruction of the infrastructure" in order to provide instant feedback. Unsurprisingly, creators are suggesting that it will be best used on bridges and piers which are typically difficult to carefully inspect, and while there's no word on when this stuff will hit DOT offices nationwide, current prototypes are panning out quite well.
