Welcome to the THz time domain spectroscopy pages of the Oxford Physics THz Group. This section of the website provides an general introduction to the tecniques and applications of THz time domain spectroscopy. The information is divided up into the following sections:
Applications: Medical, industrial, communications and security applications
