Analyzing Serial Numbers

Several techniques are available for restoring worn down serial numbers on metals. However, since these usually involve treating the metals, magneto-optical reconstructions provide a good alternative.

Magneto-optical sensor systems, such as our cmos-magview, offer a decisive advantage over conventional methods when it comes to recovering manipulated serial numbers on ferromagnetic components, vehicle identification numbers or weapons. When magnetic particles are used, the surface needs to be cleaned afterwards in a laborious process. The etching method can permanently damage the surface. In contrast, magneto-optical technology is entirely non-destructive and clean.

We have already performed a variety of tests on automotive steels, firearms, cast iron, and stainless steel to determine the sensitivity of our testing method. When inspecting vehicle identification numbers, it is even possible to search for both the worn down serial number and weld seams at the same time that have been ground back near the identification number. Nowadays, it frequently happens that serial numbers are cut out of vehicles and other serial numbers welded into their place.

Magneto-optical sensor systems such as our cmos-magvieware therefore ideal for identifying counterfeit or newly welded-in serial numbers on vehicles or weapons. Our magview hand-held deviceprovides an excellent solution especially for car dealers to protect themselves from buying stolen vehicles and help stop crime in its tracks.
