BalScan

BalScan
Average: 5 (1 vote)

The BalScan system by Laboratory Imaging has been developed for examination and comparison of markings on fired ammunition. Cartridge cases and bullets are examined, compared, scanned in 2D or 3D, and saved to a database. A special software application searches the database and displays a hit list of possible matches. The forensic expert has a full set of comparison functions at hand to confirm the match.

Wide range of calibers can be digitized in BalScan, from smallbore rifle ammunition to .12 Gauge shotgun shells. Bullets, cartridge case bottoms, or cartridge case surfaces are scanned in high 3μm resolution including 3D information. BalScan is very suitable for scanning and comparison of deformed bullets, bullet fragments and even direct scanning of the breech face and the firing pin of a firearm.

The reliable Oracle database is an important part of the BalScan system. The database is organized in two distinct forms. The database of criminal cases contains evidences related to the crime scene along with test bullets and cartridge cases. The firearms database includes fired bullets and cartridge cases linked to a particular registered firearm. The database can be installed on a standalone server connected to other BalScan workstations within a private network. Active workstations provide live examination, digitizing of bullets/cartridge cases, searching the database, and comparisons. Passive workstations (without the BalScan device) provide search and comparison only. A minimal setup contains just one active workstation which covers the complete functionality (digitization, database, comparisons).
