In this study, non-destructive evaluation using photo-mixer terahertz technique was studied to visualize the hidden damage in composite structures. A terahertz wave system was developed based on photo-mixer to detect the internal defects of the composite structure, and foreign material was simulated in a glass fiber-reinforced plastic (GFRP) specimen using PET film coated with silver nano-wire. For the visualization, an imaging algorithm for terahertz signal processing and stage control was developed using a GUI based on LABVIEW. The inspection was performed using the developed continuous terahertz inspection system and the terahertz waveform acquired in the single frequency was used to visualize defects.
