We utilize the photoexcitation of a semiconductor material as a 'reflectivity\nswitch' for a broadband terahertz field. We show that judicious use of this\nswitch enables temporal characterization of the THz field with spatial\nresolution significantly surpassing the diffraction limit of the terahertz and\nprovides desirable means for spatio-temporal terahertz spectroscopy.\n
