“…Although THz CT seems powerful, most of the published results concerned the investigation of simple manufactured phantom objects, such as foam or polyethylene cylinders, drilled with metallic bars [10,11] or filled with specific chemical substances such as lactose or lactose powder [12,13]. The main reason is the limitation caused by the diffraction effects and Fresnel losses experienced by the propagation of the THz wave through the sample.…”

A 3D continuous-wave (CW) terahertz computed tomography (CT) system employing a gas laser operating at 2.52 THz is presented. To shorten acquisition time on the premise of guaranteeing the image quality, the modified simultaneous algebraic reconstruction technique (MSART) coupled with image processing operations like the Gaussian low-pass filter (GLPF), open operation and close operation has been adopted in the paper. With the 2D results the 3D images of the samples have been also obtained. The reconstruction results illustrate the promising application prospects of this CW THz CT system.
