PC steel wires on concrete and steel bridges now visible with terahertz waves

Researchers at Tohoku University have found a way to make covered or hidden PC steel wires visible, by developing a new terahertz wave light source featuring both light and radio-wave characteristics. This new technology will be especially useful in the safety inspection of extradosed and other types of bridges that use PC steel wires hidden inside external cables covered by resin jackets. —> Read More
