Abstract
An inspection system for inspecting an enclosure and its contents using temporally gated sources of penetrating radiation. A first source produces an intermittent first beam having a duration of inactivity while a second sources produces a second beam, which may have an energy spectrum differing from that of the first beam, during the inactivity of the first beam. One detector generates a transmission signal based on penetrating radiation transmitted through the enclosure while a scatter detector generates a scatter signal based on penetrating radiation scattered by the contents of the enclosure. The scatter detector may be gated for non-detection during the pulsing of the transmission beam. A processor derives properties of the contents of the enclosure on the basis of the transmission signal and the scatter signal.
