Abstract :
We report on results of near-field pulsed THz imaging experiments with a metalized sapphire probe scanning a BaTiO3 multi-domain single crystal. The method is sensitive to the direction of spontaneous polarization, and spatial resolution is better than the dimensions of the probe at its extremity.
