Systems and methods for inspecting an aircraft

A method for inspecting an aircraft, comprising steps of:

• emitting a beam of rays from a ray source which is mounted and movable on a portal-framed structure;
• receiving and converting the beam of rays to an output signal by a detector arranged in a trench that is co-planar with the beam of rays emitted from the ray source;
• controlling the ray source to emit a beam of rays when an aircraft to be detected moves through a scanning region constituted by the ray source and the detector, and controlling the detector to receive a beam of rays emitted from the ray source that has passed through the detector aircraft;
• and
• receiving the output signal from the detector to generate a vertical transmission image of the detected aircraft.

A system for inspecting an aircraft, comprising:

• a portal-framed structure;
• at least two ray sources configured to emit a beam of rays, the at least two ray sources being mounted on a portal-framed structure and emitting beams of rays that are co-planar with each other;
• a detector configured to receive and convert the beam of rays to an output signal, which is arranged in a trench that is co-planar with the beam of rays emitted from the ray sources;
• a controller connected to the detector and the at least two ray sources and configured to control the at least two ray sources to emit a beam of rays when an aircraft to be detected moves through a scanning region constituted by the at least two ray sources and the detector, and to control the detector to receive beams of rays emitted from the at least two ray sources that have passed through the detected aircraft;
• and
• an image generation module configured to receive the output signal from the detector and generate a vertical transmission image of the detected aircraft.
