Abstract :
The first THz imaging spectrometer based on continuous-wave THz radiation is presented. The new setup is less expensive than conventional time-domain imaging systems that comprise femtosecond lasers. The system uses a two-colour external-cavity laser diode. Hence it is much more compact as compared to systems based on optically pumped solid-state lasers. As an example we investigate a human liver with metastasis
