Abstract

The aim of the European project CONSORTIS is the development of a walk-by imaging system for concealed object detections working at submillimetre-wave frequencies. This imager will allow to image a full body at two frequency bands with high sensitivity (<;1K) and large frame rate (10Hz). The imager relies on a large focal plane array with about 10k detectors operating at both bands coupled a common optical system. This contribution describes the optimization of the quasi-optical system for this imager. The proposed architecture is based on a novel flipped dual-lens design with a scan loss of less than 3dBs for both bands. This scan loss corresponds to resolution loss of only a factor 1.4 at the edge of the field of view (FoV).
