This work discusses simulation results for signal deteriorations arising from a higher carrier in a 3-line optical frequency comb based high bandwidth sampling system in terms of the key performance indicators such as root-mean-square error (RMSE), signal-to-noise and distortion ratio (SINAD), and the effective number of bits (ENOB).
To evaluate the potential of THz imaging systems for mail and luggage inspection we study a set of letters containing different hazardous items. The samples are investigated with three different THz systems available in our group: A microwave based system working around 100 GHz, a THz time-domain system and a THz gas laser. We provide a comparative discussion on our results and the advantages and disadvantages of each system.
