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.

It is no longer a question of “What can you do with a footprint?” but rather, “Who can we use to evaluate the footprint?” Cases involving pedal evidence, especially bloody footprints and issues of determining shoe sizing or fit issues compared to questioned footwear, have become more common over the past two or three years.
