Systems and methods for identifying foreign objects and debris (FOD) and
defects during fabrication of a composite structure. The system includes
at least one light source positioned to emit light that illuminates a
portion of the composite structure with bright field illumination and
that also illuminates another portion of the composite structure with
dark field illumination. The bright field illumination is reflected
differently by defects in the composite structure than from portions of
the composite structure that are defect free. The dark field illumination
is reflected differently by FOD on the composition structure than from
surfaces of the composite structure that are FOD free. The system also
includes at least one camera for receiving images of the illuminated
portions of the composite structure. The images received by the camera
may be processed by a processor which then outputs a response identifying
defects and foreign objects and debris based on the images.
