Abstract:Aiming at the debonding defect of carbon fiber reinforced polymer laminates,
an infrared phase-locked thermal imaging inspection system was established,
and the influence of different defect diameter and depth parameters on the
test was analyzed. The principal component analysis algorithm and
Karhunen-Loeve Transform algorithm are used to process the image sequence,
and the signal-to-noise ratio is calculated. It is concluded that principal
component analysis algorithm can improve the image q… Show more
