Abstract

Summary from only given. Imaging in the spectral range between a few hundred GHz and several THz holds great potential for a variety of applications including material sciences and medical diagnosis. During the last years THz technology has been developed to a stage where first commercial systems are available. Yet, the THz imaging systems developed so far all work in the time-domain using THz pulses. Hence, they rely on expensive and bulky femtosecond lasers as a key component. Here, we present the first continuous-wave THz imaging system. CW THz radiation is generated via photomixing in a LT-GaAs dipole antenna.
