| Zusammenfassung | We report spatially resolved measurements of frequency, phase, and amplitude of GHz and THz emitters employing an unstabilized THz frequency comb. Different optoelectronic detection methods are compared regarding accuracy and invasiveness. The measurement setup allows for high-precision measurements of the frequency (accuracy 9·10-14), relative amplitude (standard deviation of the mean 0.1 %) and phase (standard deviation of the mean 0.2 °). By simultaneously measuring the emission of a 30 GHz emitter as well as the emission of a CO2 laser at 28 THz, a large spectral coverage is demonstrated. Also publ. on CD-ROM. |
