摘要：
This paper shows a method to calibrating the non-uniformity of the x-ray backscatter image in a side-beam x-ray detection system. The flying spot of x-ray beam cross the luggage under detection per cycle, and every point of the detector being irradiated by flying spot can be taken as an assumed detector. Using calibrators of different thickness and combined with the corresponding mathematical model, the greyscale of the image is uniformed and calibration is achieved.
