A new millimeter-wave (MMW) imaging scheme is presented, which has potential applications for fast personal screening. The proposed design employs a special pillbox-like quasi-optics that can generate a spot beam with nearly translational scanning pattern to ensure the image uniformity. The 200-GHz heterodyne transceiver was fabricated based on a microwave vector network analyzer (VNA) to couple the MMW into the quasi-optics and to extract the return wave for imaging. Experimental results based on a prototype system demonstrate the good performance of the new imaging scheme and its capability for concealed threat objects detection.
