Detecting Erased Markings in Firearms

Using new magneto-optical (MO) sensor technology could be one way for firearm examiners to detect and restore erased markings in firearms without destroying the weapon. A recording of NIJ’s Forensic Technology Center of Excellence roundtable on the effectiveness of MO sensor technology is now available online.

Based on an evaluation of MO sensor technology’s detection and visualization of obliterated serial numbers in five different metals and one composite material, the roundtable discussed MO sensor sensitivity, accuracy, reproducibility, recovery, selectivity, and nontechnical performance factors.
