Security Imaging

Millimeter waves are able to penetrate fabrics, so weapons, explosives, and contraband can be detected even when concealed under clothing. Their wavelength of around 1mm provides fine resolution for finding small objects and, unlike conventional archway metal detectors, can also detect non-metallic threats such as ceramic knifes or person-borne plastic explosives. Active systems transmit millimetre waves and analyze the signals reflected from a person in a similar way to radar. Passive systems are similar to infra-red thermal imagers and use only naturally occurring millimetre waves to form an image.

Scan Millimetre wave imagers are now being deployed at airports to screen outgoing passengers for weapons and explosives; and also to screen incoming passengers for drugs and currency. They are also being deployed to deter and prevent theft of small, mostly non-metallic items in warehouses, distribution centers and even retail outlets for very high value goods.

Today’s systems are expensive, due to the high cost of traditional millimetre wave receivers. This also constrains the number of receivers used, and impacts the resolution and sensitivity of the system and it’s ability to detect threats. MMIC Solutions is now supplying standard millimeter wave receiver products, off-the-shelf, at the industry’s lowest cost.
