Abstract :
We proposed real-time one-dimensional terahertz time-domain (1D-THz-TDS) imaging for a moving object by combined use of non-collinear two-dimensional free-space electro-optic sampling and a line focus of THz pulse at a sample. 1D THz-TDS image of amplitude and phase with size of 2 THz by 19 mm was obtained from Fourier transform of a real-time 2D spatiotemporal THz image with size of 15 ps by 19mm.
