An inspection system based upon an enclosed conveyance such as a van, capable of road travel, for inspecting objects of inspection that may include persons. The conveyance is characterized by an enclosing body, or skin. A source of penetrating radiation and a spatial modulator for forming the penetrating radiation into a beam, both contained entirely within the body of the enclosed conveyance, irradiate an object with a time-variable scanning profile. A detector module generates a scatter signal based on penetrating radiation scattered by contents of the object, while a relative motion sensor generates a relative motion signal based on a relative disposition of the conveyance and the inspected object- An image is formed of the contents of the object based in part on the scatter signal and the relative motion signal. A detector, which may be separate or part of the scatter detector module, may exhibit sensitivity to decay products of radioactive material. |
