The discovery of more effective methods to detect and restore erased markings in firearms is of great interest to firearm examiners, in particular the invention of new non‐destructive methods. Magneto optical (MO) sensor technology may address this need. The sensor’s operating principle is the Faraday‐effect, which allows for the real‐time visualization and analysis of the magnetic distribution of sample materials. When compared to the two gold standards in serial number restoration, the MO sensor technology outperforms both in performance and utility.
