MULTIPLE SCATTER SYSTEM FOR THREAT IDENTIFICATION |
摘要 |
A system and a method for determining the density of an object. The intensity of x-rays backscattered from the object is measured by at least two backscatter detectors disposed at different distances from the intersection of an incident x-ray beam with the plane of the detectors. At least one of detectors is sensitive only to x-rays that have scattered more than once in the object, the ratio of scattered x-rays measured by the detectors being a function of the density of the scattering medium.
