Security applications

Security screening of letters, envelopes and small packages

We all know that homeland terror knows no bounds and is currently on the rise. What’s more, terror methods are becoming more ingenious and now include letter bombs that can injure or kill not only the recipient, but also mailroom and delivery staff. With the spread of the internet the information on how to make such chemical bombs has become easily accessible and even readily available. Detecting powder, liquids, explosives and other threats in small packages and mail is recently acquiring high importance. After discovering letters containing anthrax, such new threats as CBRE (chemical, biological and radiological elements) are perceived as real and require new and effective detection approaches to counter them.

Terasense offers Terahertz Imaging Scanner designed to fit the needs of industrial applications and supporting imaging at a very high speed of up to 15 m/s. It can perfectly handle security screening tasks such as checking mail packages, envelopes and small parcels for hidden objects and threats. THz images obtained in the transmission mode allow for seeing through envelopes and many types of packages, small bags, boxes, etc., and help identify potentially hazardous items inside without opening the container or disturbing its integrity.

Our THz scanner fitting most industrial conveyor systems makes mail content checking easier than ever before. Terasense technology employs Terahertz waves, which are completely harmless for people and therefore safe for operators and other staff involved in the processing/delivery cycle. If required the inspected object can be readjusted by hand, changing the field of view to obtain an optimal THz image. The technology is lightweight and portable with a small footprint that ensures problem-free deployment in small premises or constrained environments.

Designed for inspecting flat objects (envelopes, letters, small packages), our Terahertz imaging scanner represents a brand-new approach to mail screening in terms of safety, accessibility and detection. Terahertz imaging technology can detect and confirm not only hidden explosives, weapons and contraband items, but also some CBREs, solids, powders and liquids, even in small quantities.

Security screening of people

Terahertz waves are completely harmless for humans and have no ionizing radiation as opposed to X-ray machines, but can easily penetrate clothes, garments and other enclosures. Such properties make THz-based people screening solutions extremely valuable for applications where human health and safety are of utmost importance.
