We have succeeded in acquiring terahertz (THz) images at a frame rate of 1 kHz. We use intense THz pulses emitted at a repetition rate of 1 kHz from a large-aperture photoconductive antenna, and THz images were obtained at the same rate using a high-speed CCD camera. THz field images were obtained by adopting a phase-sensitive detection method. The delay time of the probe pulse of the electro-optic (EO) detection was fixed at the time when the temporal change in the THz field was steepest.
