Ballistics identification using line-scan imaging techniques

A new line-scan imaging technique, well-suited to the inspection of ballistics specimens, is presented. The proposed system addresses a number of problems associated with the imaging of cartridge cases when conventional inspection techniques are used. This particular paper deals exclusively with imaging of the cylindrical surface of cartridge cases. Imaging of the firing pin marks on the end of the case is not considered. Results obtained so far from a prototype system are presented. It should be noted that this technique is still very much in its experimental phase and that as yet it has not been fully investigated for this forensic ballistics application.
