Abstract :
To distinguish between liquids in security screening, we have applied Hilbert spectroscopy and high-Tc Josephson detectors. Compact set-ups have been developed and reflection spectra of various liquids in bottles have been measured in the spectral range of 15-300 GHz with scanning times down to 0.2 s.
