Abstract Scope |
X-Ray Computed Tomography (CT) is a widely used tool for in-situ interrogation of microstructure and geometrical characteristics of materials. It is not uncommon to observe image artifacts resulting from beam hardening due to large disparities in density between the constituents or component materials. Alternatively, similarity in densities can obscure boundaries between materials and hide discontinuities. Typical post-processing of images to address these issues use commercial software packages with proprietary processing routines that are effectively “black boxes”. The closed nature of these approaches limit continuity across research efforts and there has been limited characterization of post-processing effects on measured micro- and meso-scale properties. Here we present current efforts in developing and assessing “open” box image processing approaches for addressing beam hardening artifacts and improving material segmentation. Application perspectives will be in regard to characterizing micro- and meso-scale features of energetic materials including mono-molecular explosives, heterogenous explosive compositions, and pyrotechnics. |
