Summary:Terahertz (THz) imaging proved to be an efficient and powerful nondestructive examination (NDE) method for inspection of materials and detection of defects. Here, we present the development of a Low-Terahertz Imaging Radar(L-TIR) which is specifically designed for the evaluation of Fibre-Reinforced Polymer (FRP) composites. L-TIR will be a compact active radar with a laser pulse transmitter and a receiver which operates at the lower THz band (1 THz-2 THz). L-TIR will probe the structure and sub-layers of the FRP composites which makes it a suitable and fast tool to detect the cracks, breaks and deamination at sub-mm resolution. Keywords: THz Imaging Radar, NDE Method, FRP Composites
