Abstract: The disclosure provides a vehicle inspection system which comprises a scanning device and a vehicle transmission device extending through a scanning area of the scanning device. The vehicle transmission device is configured to drive a vehicle being inspected through the scanning area, and comprises an initial driving section located upstream of the scanning area along the moving direction of the vehicle being inspected and a self-moving section arranged downstream of the initial driving section; the initial driving section is configured to drive the vehicle being inspected to move towards the scanning device and enable the vehicle being inspected to have an initial speed upon termination of driving; the self-moving section is configured to allow the vehicle being inspected to move on by itself after termination of driving so that the vehicle being inspected will entirely pass through the scanning area. The vehicle inspection system has the advantages of simple structure and low cost.

Abstract: The present disclosure discloses a vehicle-mounted type back scattering inspection system comprising a carriage (1) and a back scattering imaging device (2). The back scattering imaging device has a vehicle-mounted working state and a ground working state, and in the vehicle-mounted working state, the back scattering imaging device performs inspection work in the carriage; in the ground working state, the back scattering imaging device performs the inspection work on the ground at the outside of the carriage; and the back scattering imaging device is separately arranged relative to the carriage and is movable between the carriage and the ground to switch between the vehicle-mounted working state and the ground working state. The back scattering imaging device of the vehicle-mounted type back scattering inspection system is separately arranged relative to the carriage and is movable between the carriage and the ground, in a scene where the vehicle cannot enter, the back scattering imaging device can move from the carriage to the ground to switch to the ground working state so as to perform the inspection work, thereby expanding the applicable range of vehicle-mounted type back scattering inspection system.

Abstract: The present application discloses a multi-view backscatter inspection system and an inspection method. The inspection system comprises an inspection passage, at least two inspection units, a control device and a data processing device. The inspection unit comprises a radiation source and a detector array. The detector array comprises at least two detector modules arranged at different positions and independent of each other. At least two inspection units are arranged so that a radiation beam from any inspection unit is directed to the outside of the detector array of each of the remaining inspection units. The control device adjusts a phase difference between radiation beams of various radiation sources, so that an effective detection area of each of the detector arrays is far away from an interference area. When an inspection image corresponding to certain detector array at certain moment is formed, the data processing device calculates an effective detection area of the detector array at the moment, processes a detection signal from a detector module within the effective detection area and forms an inspection image in which the inspection target is located at one side of the detector array at the moment. The present application may improve the quality of an inspection image.
