Micro X-ray Fluoroscopic Volumetric Digital Image Correlation System for Internal Deformation Measurements

The Weapons and Materials Research Directorate (WMRD) of the Army Research Laboratory (ARL) is seeking an"in-situ"computed tomography (CT) based volumetric measurement system that incorporates volumetric digital image correlation (VDIC) algorithms for quantitative analysis of internal deformation of targets during impact. This CT-based VDIC system will enable researchers to study deformation and failure of composite armor systems during ballistic impacts. Such a system should also benefit the study of the failure behavior in biological systems. As a result, lighter weight armor systems for both personnel and vehicles can be designed and developed. Unfortunately, such an"in-situ"CT-based VDIC system does not exist. To address this critical need, Intelligent Automation, Inc. (IAI) proposes to develop a Micro X-ray Fluoroscopic Volumetric Digital Image Correlation (MXF-VDIC) system for real-time internal deformation measurements.
