摘要： A method for monitoring objects for example for facilitating the identification and/or authentication of objects comprises: in a first recording phase: irradiating an object with a suitable source of radiation, collecting intensity information about radiation emergent from the object, resolving the intensity information spectroscopically between at least two energy bands, and storing the resultant dataset as a reference dataset; and in a second verification phase: irradiating an object with a suitable source of radiation, collecting intensity information about radiation emergent from the object, resolving the intensity information spectroscopically between at least two energy bands, and using the resultant dataset as a test dataset; identifying the object and retrieving its corresponding reference dataset; comparing the test dataset and the reference dataset within predetermined tolerance limits, and: in the event that the reference dataset and the test dataset correspond within the predetermined tolerance limits, treating the object as verified or in the event that the reference dataset and the test dataset differ by more than the predetermined tolerance limits, in a third identification phase: numerically processing the resolved intensity information from the test dataset to derive therefrom a dataset of information characteristic of the composition of the object, and using this information to identify the composition of the object.

摘要： A method processing an image dataset of radiation emergent from a test object after its irradiation by a suitable radiation source is described which comprises the steps of: generating an image dataset comprising a spatially resolved map of items of intensity data from the radiation emergent from the test object; further, resolving the intensity data items spectroscopically between at least two energy bands across the spectrum of the source; numerically processing the spectroscopically resolved intensity data items to determine a further spatially resolved dataset of data items representative of one or more orders of Compound Proton Number and/or effective mass thickness and/or a density; generating a segmented image dataset using the said dataset of data items representative of one or more orders of Compound Proton Number and/or effective mass thickness and/or a density. The method applied as part of a method for the radiological examination of an object and an apparatus for the same are also described.
