Magnetic-optical visualization of EURO banknote stripe. Magnetic code is in compliance with banknote value. |
Magnetic-optical visualization of credit card magnetic tape. Some times it is possible to identify magnetic recorder. |

|
Magnetic-optical visualization of US $100 banknote (president Franklin portrait frame). Gray-scale image embarrasses small detail resolution. |
Image after software processing. Software synthesized color image improves small detail resolution. |
|
Software allows to make automatically stitching of image frames in real time. It allows to investigate image fragments which exceed visualizer view zone.
Specification
- Effective magnetization scheme and high sensibility allow to investigate magnetic materials with small apparent magnetism.
- Fast visualizer transformation (magnetizer detachment) provides additional features: differentiation of magnetic paints by residual magnetization (high and low coercitive), indestructible investigation of objects which initially posses residual magnetization (credit cards, metal protective strips, magnetic keys).
- Software allows fast and precision measurement and comparison of investigated and control images.
