Summary:Terahertz (THz) imaging technology has been widely applied to the fields of security inspection, nondestructive testing. In this paper, the application of nonuniform fast Fourier transform(NUFFT)to the developed THz 3-D imaging system, which combines the advantages of THz and frequency modulation continuous wave (FMCW) signal, is investigated. The presented image reconstruction algorithm can increase computational efficiency compared with the conventional Omega-K (ωK) algorithm. The experimental results are illustrated to demonstrate the developed THz FMCW 3-D imaging system and the presented imaging method.
