Abstract :
We demonstrated real-time, line-field terahertz time-domain spectroscopic (THz-TDS) imaging of a moving object by combined use of electro-optical time-to-space conversion and its one-dimensional imaging. The pixel rate of the proposed system is reached to 2,320 pixel/sec, which is much faster than those of conventional THz-TDS imaging systems.
