The Applied Research & Photonics (ARP) terahertz instrumentation measures corrosion, as well as industrial and commercial coating thickness. A nondestructive, noncontact means of characterizing corrosion beneath a coating and/or coating layers’ thicknesses is accomplished by interrogating a coating system with terahertz radiation (T-ray) and utilizing the interferograms resulting from coherent and diffused reflections from different constituent layers as a function of the delay-time response at specific angle(s) of incidence. The layer-specific thicknesses are deduced by analyzing the interferograms in conjunction with the interference peak positions and some empirical modeling.
