A System for Examination of Toolmarks

ToolScan System is a complete solution for scanning, examination, and comparison of toolmarks such as: striations and imprints of plier jaws left on cylinder locks, cuts in wires, cuts in tires, test impressions in lead or toolmark castings. Plier jaws or blades can be scanned directly and compared with the marks, line intersections on signatures may be examined or broken objects may be scanned for physical match verification.

Any object with non-translucent surface can be scanned as a digital silicon casting. In this form, the 3D profile of the surface can be separated from the texture (material properties, stains) and any illumination direction can be simulated which significantly improves visibility of the toolmarks. Translucent or untypical surfaces can be scanned as all-in-focus EDF 2D images under multiple illumination directions.

The R360 variant of ToolScan includes a rotation unit which provides the ability to scan cylindrical or deformed objects such as bullets, cartridge case surfaces, wires, or any other objects up to 8 cm in diameter. The system is equipped with a set of holders for most common object shapes.

Software and Comparison
