Electro-optical control of the terahertz phase in continuous-wave photomixing terahertz systems allows the determination of both terahertz amplitude and phase with a single sampling point per frequency. It is experimentally demonstrated that spectroscopic measurements can be performed by an order of magnitude faster with the single sampling point method without performance degradation compared to the standard delay line technique.
