A radiographic inspection system (10) and method for aircraft fuselages (12) includes a radiation source (16) located on one side of a fuselage (12) and a radiation detector (18) located on another side of the fuselage (12) and positioned to receive radiation from the radiation source (16). Precise manipulators (22,24) are provided for simultaneously moving the radiation source (16) and the radiation detector (18). The source (16) and detector (18) are moved under control of a controller (20) so that the projection of radiation from the radiation source (16) onto the radiation detector (18) from a selected plane of the fuselage (12) stays constant and the projection of radiation from the radiation source (16) onto the radiation detector (18) from other planes of the fuselage (12) varies. The controller (20) processes radiation detected by the radiation source (16) so as to produce a laminographic image having a field of view in a selected plane of the fuselage (12). The laminographic image is displayed on a display (21). <IMAGE> |
