摘要：

Terahertz spectroscopy of paint films has been studied in a range from 0.1 to 18 THz. The paint layers in actual use showed strong-absorption at higher frequency range, however they showed transparent characteristics in sub-THz range. Hence, sub-terahertz imaging of a painted steel plate as a method of nondestructive inspection was performed using a wave ranging from 100 to 200 GHz. An invisible rusty area covered with multiple paint layers on steel in actual use was effectively detected by power-reflection imaging.
