Abstract
A cargo security inspection system inspecting an object moving through the system, including: a mechanical conveyance unit carrying, conveying, and defining a travel path of the object in the system; a radiation-generating unit generating ray beams for transmitting through the object; and a data collecting unit collecting transmission data about the rays having already transmitted through the object and processing the transmission data; wherein the travel path includes at least two linear sub-paths at an angle relative to each other; the data collecting unit includes at least two detector arrays receiving ray beams, each detector array corresponding to one linear sub-path, a receiving plane of each of the detector arrays disposed parallel to its corresponding linear sub-path; and in use, the radiation-generating and data collecting units remain stationary, and the object travels along its travel path and only translates on the at least two linear sub-paths without any rotation.
