| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Terahertz wave has been expected to be a novel non-destructive inspection tool especially for metals shielded by insulating polymer, for example insulated copper cables and painted steel because terahertz wave has high transmittance for polymers and high reflectance from metals. Terahertz reflection imaging was applied to copper plate sample that had been artificially cracked. It was shown that a crack in the copper plate surface can be clearly seen by a decrease in the intensity of the reflected signal, and that variable size crack can be quantitatively detected. This result will be useful for terahertz practical application as a non-destructive inspection tool. | |
