MMW and THz sensors offer unique imaging capabilities and challenges. This paper will provide a brief discussion of illumination, propagation, and resolution in these and adjacent bands, followed by a discussion of some application areas for these sensors, in particular imaging in Degraded Visual Environments (DVE), stand-off screening and chemical detection, and surveillance and monitoring. Comparisons with other sensing modalities will be provided discussing some of the relative strengths and weaknesses of MMW and THz sensing compared to these other modalities.
