The effects of transceiver antenna alignments on THz holographic imaging system

In this paper, we report our experimental work on a terahertz holography system operating at 220 GHz. The theory of microwave holography is introduced briefly. The common images and holographic images are compared. Two quantitative variables are adopted here to assess the quality of images and the performance of different horn antennas settings is studied. The results achieved in this study provide a reference for further holography researches in terahertz band.
