Abstract

Systems and methods for determining an inconsistency characteristic of a composite structure, such as inconsistency density-per-unit area. In one implementation, a method is disclosed for determining an inconsistency characteristic of a composite structure. The method involves determining a first distance from a first reference point of the composite structure to an inconsistency; determining a second distance from a second reference point of the composite structure to the inconsistency; using the first and second distances to establish a reference area of the composite structure; and considering each inconsistency detected within the reference area and producing therefrom an inconsistency characteristic representative of the composite structure.
