Abstract : In the High-Resolution Three-Dimensional Computed Tomography (HR3DCT) program, a team comprised of Perceptics, Skiametrics, Alliant Techsystems, Lockheed Martin, and Tufts University demonstrated that HR3DCT is a viable and valuable technology for large (SRM) bondline inspection. The approach used a specially built test apparatus, the HR3DCT breadboard, to test underlying assumptions and to apply the HR3DCT algorithm to a variety of test objects. At the completion of this effort, HR3DCT's few limitations and its remarkable potential were better-understood. The bondlines of a Titan SRM segment and a simulated Titan IV segment (both three meters in diameter), a 1.8-m diameter strategic SRM, and a Minuteman third-stage dome. In each case, the reconstructed data exhibited sensitivity comparable to conventional (CT). Bondline resolution was superior to conventional CT. Reconstructions were three-dimensional, facilitating immediate apprehension of bondline condition.
