HARDWARE AND SOFTWARE SYSTEM
FOR FORENSIC EXAMINATION OF FIREARMS AND AMMUNITION SERIAL NUMBERS
REGULA 7517

Function

Firmware is intended for forensic examination of firearms and ammunition serial numbers with the following purposes:
  • serial numbers authenticity verification;
  • recovery of initial numbers in case of any damages in their relief (corrosion, scale, wear, etc.);
  • recovery of initial numbers in case of their removal;
  • general trace evidence examinations and non-destructive testing of relief and stresses in the surface layer of metal objects.

Delivery set

Magneto-optical device
«Regula 7517A»

USB-device for magneto-optical imaging (MOV) of magnetograms - magnetic tapes with records of defectoscopic data of the relief and structure of surface layers of objects.
The MOV process is based on the use of the Faraday magneto-optical effect
For image input, stitching and processing program NUCA is used.

Methods

  • Excitation of magnetic scattering fields of the investigated object (associated with the surface relief and internal stresses) by the action of an external source of a constant or alternating magnetic field;
  • Copying of induced magnetic fields of scattering of the object under investigation into an intermediate flexible magnetic carrier;
  • Magneto-optical visualization of magnetic copies of the induced magnetic scattering fields of the object under investigation with the help of the magneto-optical Faraday effect arising in crystalline films of B-containing ferritgrants;
  • Automatic input and processing of magneto-optical images of objects obtained by the methods listed above into a personal computer, the study of images obtained by means of special software: measurements, comparison, etc.

Features

  • The magneto-optical device "Regula 7515A" is made as a desktop version that provides a compact placement of the complex in a laboratory applications;
  • The "Regula 7515C" magnetization device allows performing the research of weapon samples of various models: various in shape, size and cross-sectional area of the number pad;
  • The device of eddy current magnetography "Regula 7515Â" is an improved version of the model "Regula 7515M", adapted for examination of firearm toolmarks, and different: an extended range of excitation signal, replaceable and adjustable magnetic groups, the ability to perform static magnetic copies (which is important in the study of remote marking on a complex surface relief).
