Abstract： |
The invention relates to a method and device of radiating scanning with multi energies. It comprises detecting value after penetrating the tested material, preliminary judging the feature and thickness information of the material, selecting the energy interval and settlement function of the material, finally deciding the material contained and adjusting the image based on the thickness information. The corresponding device comprises ray source generating multi energies, energy spectrum adjusting device, detecting matrix for varied energy, and corresponding image settlement mechanism. It can be used for unpacking inspection. |
