Abstract

An inspection system is for inspecting an object with penetrating radiation. A source of penetrating radiation provides a beam of radiation. The beam alternates between a first beam shape and a second beam shape, the first and second beam shapes being coplanar. A first detector arrangement is for detecting penetrating radiation from a portion of the beam transmitted through the object and generating a transmitted radiation signal. A second detector arrangement is for detecting penetrating radiation from a portion of the beam scattered by the object and generating a scattered radiation signal. A processor determines at least one characteristic of the object based at least on the transmitted and scattered radiation signals.
