Abstract :
This paper presents three-dimensional tomographic imaging system by using low-coherence terahertz (THz) sources. In contrast to conventional THz-pulse tomography with femtosecond pulse lasers, the proposed method requires compact and low-cost broadband optical signals such as amplified spontaneous emission (ASE) sources. Operation principle and the first experimental demonstration of tomographic imaging using 300-GHz-band sources are shown.
