System for inspecting the contents of a container

A system for inspecting the contents of a container, the system comprising:

• a first apparatus for emitting sequential beams of penetrating electromagnetic radiation from a target in a first set of substantially parallel directions;
• the first apparatus including:
• a source for producing a beam of charged particles,
• a target having a surface which receives the beam of charged particles and emits electromagnetic waves in response thereto,
• an electromagnetic beam director that directs the beam of charged particles to a plurality of specified locations on the target,
• an electromagnetic steering device disposed proximal to the target, the electromagnetic steering device directing the charged particles to strike the target at a substantially ninety degree angle to the surface of the target, and
• a collimator, the collimator having an array of transmitting regions and being disposed proximal to the target such that electromagnetic wave emitted from the target pass through the collimator and emerge from the array of transmitting regions in a series of parallel beams;
• a conveyor for moving the container relative to the first source;
• a first detector for detecting the penetrating radiation after interaction with the contents of the container and generating a first set of signals corresponding to each of the substantially parallel directions;
• and
• a controller for characterizing the contents of the container based at least on the first set of signals.
