Abstract

To overcome the limitations of traditional reflective radar in tomographic imaging of objects with large curvatures, we introduce a broadband terahertz computed tomography (CT) imaging method. Based on the principles of computed tomography, we designed and constructed a broadband terahertz CT imaging system operating in the frequency range of 150-220 GHz. By integrating the filtered back-projection algorithm, the system successfully achieved three-dimensional reconstruction of typical objects, with a diameter measurement accuracy of up to 2 mm.
