Method and Apparatus for Detecting and Locating Delaminations in a Transparency.
Abstract
A system and method for detecting and locating defects, such as delaminations, in a multi-layer laminated transparency includes a housing having top and bottom diagnonally spaced openings with a lamp mounted in the housing for generating a light-emitting object. Optical reflections of an image of the object from interface surfaces, as well as from top and bottom surfaces, of the transparency are observed for determining the presence of a delamination in the transparency. A delamination is located by identifying a reflected image from an interface surface which is approximately as bright as reflected images from the top and bottom surfaces of the transparency.
