Abstract :
This paper presents a terahertz (THz) tomographic imaging system using monochromatic 400~800-GHz signals, which have been generated and swept by photonic techniques. Measurable thickness of plastic plates has been experimentally verified as small as 0.37 mm, which corresponds to a depth resolution of 0.61 mm in the air.
