Abstract
Methods of fabricating extra-mural absorption elements adapted for incorporation in an image-conducting optical fiber array include fabricating various constituent components to be included in an optical fiber bundle from one or more reducible-ion-containing glasses. Various components fabricated from a reducible-ion-containing glass are selectively exposed to a reducing atmosphere such that they are reduction-blackened prior to at least one heating and drawing step relative to the bundle into which they are to be fusedly incorporated. Such 'pre-blackened' components function as extra-mural absorption media throughout the length of an image-conducting optical fiber array and alternatively include fiber claddings and substitutional and interstitial extra-mural absorption elements.
