Abstract
A terahertz spectroscopy system comprises a tenahertz source for illuminating, in use, a sample with a pulse of radiation in the terahertz frequency range. Excitation means provides excitation energy in the form of an electromagnetic or acoustic wave during illumination of the sample by the terahertz source and a terahertz sensor receives energy from the illuminated sample. Processing means receives signals from the terahertz sensor and processes them to provide an output representative of the terahertz spectrum received by the sensor.

A terahertz spectroscopy system comprising:
- a terahertz source for illuminating, in use, a sample with a pulse of radiation in the terahertz frequency range;
- excitation means for providing excitation energy in the form of a beam on a selected portion of the illuminated sample prior to or during illumination of the sample by the terahertz source;
- a terahertz sensor for receiving energy from the illuminated sample;
- and
- processing means for receiving signals from the terahertz sensor and processing them to provide an output representative of the terahertz spectrum Preceived by the sensor.
