  • Patent number: 7724869
    Abstract: Disclosed is a detector array comprising a first linear array for detecting a first ray and a second ray which penetrate through a first plurality of parts of the inspected object to acquire first values and second values for the first plurality of parts, wherein the second ray is alternately emitted with the first ray; and a second linear array arranged parallel to the first linear array for detecting the first ray and the second ray which penetrate through a second plurality of parts of the inspected object to acquire third values and fourth values for the second plurality of parts, wherein the first plurality of parts is partly identical to the second plurality of parts. With the detector array, the efficiency and material discrimination accuracy can be improved in the scanning inspection of the inspected object by use of alternate dual-energy rays.

  • Patent number: 7702075
    Abstract: Disclosed are an energy spectrum modulation apparatus, a material discrimination method and a device thereof, as well as an image processing method are disclosed, which can discriminate the material in large- and medium-sized objects such as cargo containers, air cargo containers, etc. by using X-rays having different energy levels. The energy spectrum modulation apparatus comprises a first energy spectrum modulation part for modulating a first ray having a first energy spectrum, and a second energy spectrum modulation part coupled to the first energy spectrum modulation part and for modulating a second ray having a second energy spectrum different from the first energy spectrum. The present invention can be used in the non-opening inspection for large-sized container cargo at places such as Customs, ports and airports.

  • Patent number: 7580505
    Abstract: The present invention discloses a method for inspecting an object using multi-energy radiations and an apparatus thereof. The method comprises the steps of: causing multi-energy radiations to interact with an object under inspection; detecting and recording detection values after an interaction between the multi-energy radiations and the object under inspection; substituting a portion of the detection values into a predetermined calibration function to obtain information comprising primary material attribute; and determining further material attributes of the object by applying a set of functions suitable for a energy band corresponding to the information. The present invention is applicable to the large container cargo inspection without opening containers at customs, ports and airports.
