1. An apparatus for inspecting an object, comprising:

  • a first stage inspection system comprising a conveyor for transporting the object into a first inspection volume, a dual energy X-ray source wherein said dual energy X-ray source is configured to irradiate said first inspection volume with dual energy radiation, and a detector array positioned opposite said dual energy X-ray source, configured to receive dual energy radiation transmitted through said object, and adapted to generate signals, comprising high energy data component and low energy data, based upon said received dual energy radiation; and

    at least one processor for processing said signals to generate a three dimensional image of said object and to locate a threat within said object and for plotting said high energy data against said low energy data to identify at least one of spectra, parameters of analytical expressions, or spectral attenuation functions in a lookup table.
