Quasi-optical (QO) reflectometer of internal reflection (IR) on the basis of a hollow dielectric beamguide (HDB) and a number of beamguiding components and devices of THz frequency range is developed. The reflectometer is tested for detection of surface contaminations and sub-surface damages of carbon fiber reinforced plastic (CFRP). The results of the study of CFRP samples with different contaminations in sub-THz frequency range (0.1…0.2) ТHz are shown.
