The Terahertz (THz) frequency band has traditionally been of interest for the past 30 years in astronomy. However, recent advancements in technology in this band have sparked interest in other applications such as security. The THz frequency band is specially suited to this task, given that it has the penetration aspects of higher frequencies without the harmful ionizing effects. Although the area of airport security systems has seen new developments in hardware and commercial products, it is still largely underdeveloped in terms of efficient software. There are two potential considerations for efficiency in this area: personal privacy and detection speed. Both are addressed in our research.
