| Abstract Scope |
X-Ray Computed Tomography (CT) is a valuable tool for in-situ, non-destructive interrogation of heterogenous granular materials. Last year we “opened” Pandora’s box by discussing the challenges of closed image processing tools for quantitative material characterization using CT images. Here we present current efforts in developing “open” box image processing techniques, the validation of these techniques, and the use in quantification of heterogenous granular materials. Application perspectives will be in regards to the characterization of micro- and meso-scale features of energetic materials including mono-molecular explosives, heterogenous explosive compositions, and pyrotechnics.
