Magneto-Optical Sensor Roundtable

Magneto-Optical Sensor Roundtable


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 nondestructive methods. Magneto optical (MO) sensor technology may address this need. Earlier in 2014, the FTCOE released a report on this technology evaluating it for the detection and visualization of obliterated serial numbers in five different metals and one composite material. During this roundtable the researchers will discuss their findings, including: MO sensor sensitivity (detection limit), accuracy, reproducibility, recovery, and selectivity. Non-technical performance factors included sample preparation, system operation, sample processing, worker safety and cost.

A certificate of completion is available for all who register and attend this webinar.
