A 3D continuous-wave (CW) terahertz computed tomography (CT) system employing a terahertz sources (IMPATT diodes) operating at 278.6 GHz is presented. To shorten acquisition time on the premise of guaranteeing the image quality, the algorithm minimizes the total variation (TV) is used to reconstruct the THz-CT results of zero order Bessel beam. With the 2D results of the samples have been also obtained.
