摘要

In the paper the possibility of using of backward-wave oscillator (BWO) terahertz (THz) system for detecting of hidden images is presented. THz image of a hidden test logo behind an optically opaque sheet at frequency 0.9 THz is obtained. Based on the intensity contrast filtering, the technique of drawing the logo image on the paper surface is shown.
