About Engineering

Center for Nondestructive Characterization Ultra-Wide Band Communication Ultra-Wide Band Sensors				The Center for Nondestructive Characterization's near-term strategic mission objectives are to advance Engineering's core competencies and technologies in the following three areas: Quantitative nondestructive characterization. Our goal is to be able to quantitatively evaluate physical properties such as microstructure, density, elemental and molecular composition, mechanical properties, stress state, geometry, thermal properties and radioactive assay in three dimensions as a function of time. These properties should have 0.1% accuracy.
		Fast nanoscale imaging. Fast nanoscale imaging will provide many programs with quantitative multidimensional (>3-D) imaging down to nanoscale lengths. We want to develop NDC techniques that can obtain spatial resolution of 100 nm (resolving two objects separated by 100 nm) over a 1-mm field-of-view. NDC-to-physics understanding. The objective is for NDC to become an integral element in the design, manufacture, analysis, and verification of parts and systems. The quantitative NDC data obtained in this process should be artifact-free to facilitate creation of finite element meshes for "as-built" modeling.
