There are many methods of examination of coating failures. This paper presents application of a Terahertz Time Domain Spectroscopy for inspection of thin nonconductive coatings. Results of preliminary tests and results of inspection carried for various kinds of coatings were presented. The coatings containing selected kinds of defects were also prepared and evaluated. The presented results show that the terahertz method can be a good alternative in case of coatings testing.
