Highly sensitive technology for passive detection

A newly developed sub-millimetre wave imaging technology offers increased sensitivity for passive detection through obstacles such as clouds, wall, soil and clothes.
Highly sensitive technology for passive detection
This Finnish innovation is based on cryogenically cooled (4˚K), broadband antenna-coupled, superconducting hot-spot micro-bolometers that are highly sensitive. The technology can be employed for passive detection of sub-millimetre wave radiation as in security screening applications.

In comparison to other competing technologies such as heterodyne receivers that use active sub-millimetre illumination, the sub-millimetre wave imaging systems are simpler and less expensive. Additionally, the latter are more practical in their application since reflections, which is the most common problem of such contemporary technologies, are absent.

The patented technology can be of increased assistance in the fields of visioning and imaging through clouds, fog, walls, soil and clothes. Such applications include airport air control particularly under conditions of low visibility, detection of mines in the ground and weapons through clothes in airport security.

Industrial partners in the areas of security and/or imaging technology are sought for further collaboration including the development of further applications and the exploitation of the existing know-how.
