Abstract:
1. A THz measurement system comprising: a THz transmitter having a light-sensitive element; a THz receiver having a light-sensitive element; and an arrangement for generating a signal having a variably adjustable time position or phase position, the arrangement including: wherein the THz transmitter and THz receiver are configured to be activated by the beat note signal or by a decoupled portion of the beat note signal or by an optical signal which results by reshaping of the beat note signal or of a decoupled portion of the beat note signal, the arrangement further including a coupler connected before the phase modulator for decoupling a portion of a beat note from the first and second light components not yet modulated by the phase modulator, with either the THz receiver being activated by the portion decoupled before the phase modulator and the THz transmitter being activated by the beat note signal exiting the phase modulator or the THz transmitter being activated by the portion decoupled before the phase modulator and the THz receiver being activated by the beat note signal exiting the phase modulator.
