Abstract
A method for determining and verifying ply orientation of composite laminates includes performing a first scan of a prepared edge of a composite laminate using an off-axis inclined light source directing light at a first acute angle to a first area on the prepared edge to produce a first scanned image; rotating an orientation of the off-axis inclined light source relative to the prepared edge, such that the off-axis inclined light source directs light at a second acute angle symmetrically opposite the first acute angle; and performing a second scan of the prepared edge using the off-axis inclined light source directing light at the second acute angle to the first area on the prepared edge to produce a second scanned image. The method includes comparing the first and second scanned images to determine a ply orientation of each ply, and verifying the ply orientation against a baseline ply orientation.
