Abstract :
Submillimeter waves have unique optical properties that allow for applications in the security domain. Especially the high transmission through clothing combined with low transmission through many materials that can be used to build harmful objects enables applications in security screenings. We already showed that it is possible to acquire passive images at 350 GHz with a cooled system based on superconducting detectors working at 500mK. Now we present recent results of our current development of a new prototype of a passive submillimeter video camera for security applications. Compared to its predecessor, it has a larger field of view and can take images at frame rates up to 25 Hz.
