Abstract
An inspection system for detecting the presence of selected crystalline materials, such as explosives or drugs, utilizing an x-ray source and a collimated array of detectors to sense radiation scattered by the objects being inspected. A signal processing system compares the measured signal with selected spectra to determine whether specific materials are present within the inspected object.
Claims15
A method of inspecting parcels to detect the presence of selected crystalline materials in the presence of other crystalline and noncrystalline materials comprising:
- generating x-ray radiation from a source;
- conveying a parcel containing crystalline and non-crystalline materials to be inspected continuously past the source to irradiate the materials with the radiation;
- detecting radiation scattered by crystalline material within the parcel at a predetermined angle;
- and
- analyzing a spectrum of the detected radiation to detect the presence of a selected crystalline material on or within the parcel.
