Flying above danger

Whether it is the eerie setting of an abandoned nuclear power plant, or the chaotic scenes of an active warzone, there are areas in the world considered too dangerous to travel in without assistance. Instead, we often rely on a range of robust technologies that are able to enter these hazardous environments and obtain accurate data without putting lives at risk.

The emergence of unmanned aerial vehicles (UAVs), or drones, in recent years has created a cost-effective means of sending various analytical tools into dangerous areas.

Can higher powers open windows for terahertz security?

As of today, terahertz imaging and sensing is yet to fully live up to the hopes that potential users in security applications might have had for it. The term terahertz became popular among spectroscopists referring to the electromagnetic spectrum between the infrared and microwave in the 1970s. Interest from researchers in using technology producing and detecting such light for identifying hidden threats grew through the 2000s, as better terahertz sources became available.
