Expert investigations of magnetic protection elements of documents:

• magnetic map of documents sewing and analyze;
• comparative investigations of print materials and methods:
• detection of presence or absence of magnetic properties in researched objects;
• investigation of touches (magnetic paints, fibers, tapes and others types of magnetic protection elements): form, size and disposition;
• assessment of magnetic characteristics of document protection elements (distribution of magnetic induction, module of magnetic flow);
• invisible magnetic strokes reading;
• damaged documents researches: stained and spilled texts reading, which are printed with magnetic paint.

Magnetic map of $100 banknote demonstrates disposition of magnetic paint on banknote

Comparison of magnetic induction histograms allows to separate paint of authentic (green, red) and forgery (blue) banknotes

Methods magnetization by external magnetic field; compensation of object stray field by magnetic field of external source. magneto-optical visualization of stray field of object by using Faradey's effect; visualized image transformation to digital video signal; magnetization by external magnetic field; compensation of object stray field by magnetic field of external source; magneto-optical visualization of stray field of object by using Faradey's effect; visualized image transformation to digital video signal; digital image processing, including images comparison and its angle, linear and amplitude characteristics measurement,

Characteristics maximum size of the investigated document - 335 x 297 mm (format А3+); field of vision of the optical input system: 18.5 х 15 mm (640 х 512 / 1280 х 1024 pixels) , image point size: not worse than 29/14 mkm; scanning time of A4 format document: not more than 5.5 min; computer interface: USB; power supply source: less than 40 W; overall dimensions: less than 586 х 470 х230 mm; weight of scanner with power supply unit: 15.5 kg.

Features effective scheme of magnetization and high sensitivity of scanner allows to investigate materials with small level of magnetic flow. detachable magnetization system allows to distinguish magnetic protection elements made of hard magnetic and soft magnetic materials; special software allows fast and precision measurement or comparison of test object and specimen. scanner is further development of SEZAM , MagReader., MagMouse., with essentially better characteristics.
