IMPACT OF DAMAGED SURFACE ON COHERENT FIBER OPTIC BUNDLE ON THE RESOLUTION OF THE IMAGES

IMPACT OF DAMAGED SURFACE ON COHERENT FIBER OPTIC BUNDLE ON THE RESOLUTION OF THE IMAGES

Maciel, Ana Luiza Cantharino ; Ramalho, Jéssica Guerreiro Santos ; Silva, Valéria Loureiro da ;

Full article:

This study investigates the effects of surface scratches resulting from manual polishing on the resolution of images formed by optical fiber bundle. Size controlled scratches were introduced to the bundle's surface, and images were collected while gradually increasing the scratch severity. The results show that while scratches reduce light transmission and contrast, the resolution is more affected by the object-fiber edges alignment than the polishment scratches.
