基于跳点扫描转筒技术,我们设计开发了背散射成像系统,系统框架示意图如图1所示,目前该系统在调试中。该系统主要分为5大部分:X射线源、转筒模块、数据采集与传输模块、主控制与处理模块、电源模块。背散射成像系统的工作过程如下:首先低能X射线源发出的X射线,经过跳点扫描转筒系统后打到要检测的物体上面(在每个时刻,只有一个X光子穿过跳点扫描转筒);X射线在和物体 Based on the jump-point scanning drum technology, we designed and developed a backscatter imaging system. The schematic diagram of the system frame is shown in Figure 1, and the system is currently under debugging. The system is divided into five major parts: X-ray source, drum module, data acquisition and transmission module, the main control and processing module, power module. Backscatter imaging system work process is as follows: First, low-energy X-ray emitted by the X-ray source, after jumping point scanning drum system hit the object to be detected (at each moment, only one X-ray through the point scan turn Tube); X-ray and object
