Abstract
Sub-terahertz imaging for construction materials has been performed using room-temperature operating oscillators. Invisible defects in woods, and mixed foreign bodies and cracks in concrete were detected effectively by power transmission imaging. In addition, rusty area covered with paint on the steel was distinguished by power reflection imaging. So, Sub-terahertz imaging is one of the promising tools for the safe structural engineering.
