Forensic Optical Topography

The Forensic Technology Center of Excellence recently released a new landscape study on Forensic Optical Topography and its relevance to firearm identification.

The field of firearms identification is undergoing a major change in technology and capability with the introduction of optical topography into forensic laboratory practice. Optical topography provides a three-dimensional (3D) view of the surface of a bullet or cartridge case at resolutions that capture the full range of subclass and individual characteristics. This technology offers an additional method to the comparison microscope for one-to-one firearm evidence comparisons, and may provide an objective measurement of similarity toward a possible source identification.
