THz pulse generation and real-time THz imaging

摘要

Terahertz electromagnetic pulse generation using photoconductive emitters, their characterization, real-time imaging, and spectroscopies using them are described. Intense THz pulses were generated using a large-aperture photoconductive antenna. Real-time imaging were performed for the pulse characterization and acquisition of 1-kHz high-speed movies of moving objects. Tunable THz pulse generation and ultrafast semiconductor spectroscopy using photoconductive antennas will also be described.
