【 摘 要 】

Terahertz (THz) imaging is a relatively new field of optical engineering and physics. Despite it has been already used in such directions as biomedical imaging, non-destructive evaluation of materials, and security detection of concealed objects, there are many problems in the development of them, connected with low efficiency of imaging sources and detectors. A new type of THz imaging system was implemented, based on backward wave oscillator THz source. Its efficiency of detecting concealed objects was shown.
