Abstract
A terahertz (THz) imaging system based on air ionizing in two color laser fields is demonstrated. A 1mm thick (110)-oriented ZnTe is used for electro-optic sampling crystal. The depth of modulation of THz is 0.8%, which is much lager than that of optical rectification in ZnTe. Minus the background, the transmission images of the THz focus and a moving metal rod are demonstrated. The imaging speed is 34 fps. It is very useful to observe the movement of objects with terahertz in real time.
