Abstract
Time-domain terahertz spectroscopy (THz-TDS), based on optoelectronic generation and detection of sub-picosecond electrical transients in photoconducting antennae, has become an extremely valuable tool for spectroscopy in the far-infrared spectral region,1 Recently, we have extended THz-TDS to realtime “T-ray” imaging by reducing the acquisition time of THz waveforms by four orders of magnitude.
