Patent Images
1. A mobile inspection vehicle comprising:
- an X-ray scanning system comprising an X-ray source and a plurality of detectors for obtaining a radiographic image of an object located outside the vehicle;
one or more sensors adapted to obtain surveillance data from a predefined area surrounding the vehicle;
a range finder for determining a distance from at least one of the plurality of detectors to an area on a surface of the object and adapted to cause a beam of light to be transmitted to the area on the surface of the object and detect light reflected from the area on the surface of the object; and
a processor configured to process the obtained radiographic image, wherein the processor is configured to apply an intensity correction to the obtained radiographic image based on the determined distance.

Abstract
The present specification discloses a covert mobile inspection vehicle with a backscatter X-ray scanning system that has an X-ray source and detectors for obtaining a radiographic image of an object outside the vehicle. The systems preferably include at least one sensor for determining a distance from at least one of the detectors to points on the surface of the object being scanned, a processor for processing the obtained radiographic image by using the determined distance of the object to obtain an atomic number of each material contained in the object, and one or more sensors to obtain surveillance data from a predefined area surrounding the vehicle.
