CT技术用于工业无损检测大致始于70年代中后期.最初的研究工作是在医用CT上进行的,检测的对象为石油岩芯、碳复合材料及轻金属结构等低密度试件.由于医用CT射线源穿透能力有限,机械扫描系统专门为人体设计,在检测高密度及大体积物体方面存在着明显局限性.从70年代末到80年代初,美军针对飞机高级涡轮叶片及火箭发动机的检测,提出并实施了几个重要研究计划,对工业CT技术的发展起了推动作用.例如,1981年10月,美国莱特-派特森空军基地的空军航空系统部资助美国ARACOR和喷气战略推进公司共同研制用于导弹和固体火箭发动机部件检测的工业CT系统,项目总经费460万美元,包括两套系统.第一套称为AF/ACTS I,采用420kVX射线源,可检测直径lm物体,于1983年3月安装,
CT technology for industrial non-destructive testing generally began in the late 1970s. The initial research work was carried out on medical CT, the detection of the object for the oil core, carbon composite materials and light metal structures and other low-density specimens. As medical CT Ray source has limited penetrating ability and the mechanical scanning system is specially designed for the human body and has obvious limitations in detecting high-density and large-volume objects. From the late 1970s to the early 1980s, the U.S. military’s inspection of advanced turbine blades and rocket motors , Several important research projects were put forward and implemented to promote the development of industrial CT technology.For example, in October 1981, Air Force Aviation Systems Division of Wright-Patterson AFB funded the United States ARACOR and Jet Propulsion Company Jointly developed industrial CT system for the detection of missile and solid rocket engine components, the project total funding of 4.6 million US dollars, including two systems.The first set called AF / ACTS I, using 420kVX ray source can detect lm diameter objects, at March 1983 installation,
