Abstract
Terahertz imaging can be used as a vital tool for non-destructive evaluation of internal structure and defects in concrete. Here we show successful detection of internal defects in concrete samples using THz imaging. This method gives higher resolution images than conventional Radar and has higher penetration depth compared to Infrared tomography.
