  • Page 4: Function

    Magneto-optical visualizer (hereinafter referred the «visualizer») Regula 4197 is intended for expert examination of document magnetic protection. The device visualizes images executed with magnetic inks, tapes, fibers and other magnetic materials. The visualized images are displayed on a PC monitor and can be stored as files of normal raster graphic formats.

  • Page 5: Device Design

    DEVICE DESIGN Visualizer Regula 4197 consists of the following components (Figure 1): an optical electronic block 1 and a magnetic excitation system 2. The right 3 and left 4 functional buttons and a LED indicator 5 are located on the top of the optical electronic block.

    User’s guide Test object DESCRIPTION OF DEVICE OPERATION The magneto-optical visualizer Regula 4197 is a USB device. Its power supply, control, output and processing of examination results are carried out with the help of a PC. The visualizer is to be connected to one of PC USB-ports.

  • Page 7: Operation Order

    located inside the device. After special preliminary processing, the image is output to the CADR application window. Near the sensitive element there is an inductor. In certain visualizer operation modes, it generates series of magnetic impulses affecting the sensitive element. The inductor is intended to increase sensitivity of the visualizer, improve image quality and to generate magnetic displacement fields used in the mode assessing magnetic parameters of document security features.
  • Page 8 PC operating system requires installation of the visualizer driver. For more details see paragraph 6.2). Visualizer software installation The software supplied with Regula 4197 visualizer includes: 1) CADR application, 2) visualizer driver. The procedure of software installation is the following: Insert the installation medium with the visualizer software into the disk drive or USB port of the PC.

  • Page 9: Operation Execution

    When installation is complete, open the Device Manager window to check that a new device «Magneto-optical Visualizer 4197» has appeared in the «Forensic Devices» section. Make sure that the device is installed correctly (without «?» or «!» marks in the Device Manager panel) .
  • Page 10 Put the visualizer on the examined document with the sensitive element facing downwards. Not all documents are printed using magnetic ink. So if there is no document with magnetic security features at the initial startup of the device, use the test object from the visualizer delivery set to check device operation.

  • Page 12: Background And Frame Input Options

    To switch the format, select the menu item [File] -> [Videodriver] -> [Video format] (Figure 6). Figure 6 Background and frame input options The visualizer can operate in several modes that allow obtaining images of different quality. But the modes in which high-quality images are captured require more time to form a frame.
  • Page 13 contact with the magnetic image of the examined document. Then the program subtracts the background from the frame. As a result, in the obtained image, the user can see only the document magnetic image against a solid gray background. Such technology allows filtering possible noises, artifacts and brightness irregularities which the initial (background) image formed by the magneto-optical crystal may contain.

    once. Afterwards, the background is subtracted from this frame. This operation mode is the most simple and quick. Discovery — a background image is input twice. Then the arithmetic mean of those two images is used as the background. It means that two brightness values of each pixel are summed up and divided by two.

  • Page 17 Assessment of magnetic parameters The «Magnetic measurements» function of the CADR software is intended for assessing magnetic parameters of the materials used to produce document security features and for comparing these parameters in examined documents and in templates (certainly authentic documents) for a further conclusion about a probable forgery.
  • Page 18 To call the «Magnetic measurements» function, left-click on the E button (Figure 9a) or left-click in the menu [Modules] -> [«MagMouse / Regula 4197»] -> [Magnetic measurements] (Figure 9b). Before running the «Magnetic measurements» function, input a background image as described in paragraph 6.3 (Button A, Figure 7).

  • Page 21 Figure 9d ATTENTION! TO ACHIEVE ACCURATE COMPARATIVE ASSESSMENT OF MAGNETIC PARAMETERS, MAKE SURE THE CONTROL AREAS OF EXAMINED AND REFERENCE DOCUMENTS COINCIDE . WHEN CHOOSING THE CONTROL AREA, THE AREAS WITH HIGHER PRINT DENSITY AND THICKER INK LAYER ARE PREFERABLE . When examining crumpled documents and banknotes, press the visualizer manually to provide close magnetic contact between the document and the visualizer.

To perform the «Magnetic remeasurements» function: activate the window with this image by clicking on it once. perform the «Magnetic remeasurements» function from the CADR menu: [Modules] -> [MagMouse/Regula 4197] -> [Magnetic remeasurements]. As a result of «Magnetic remeasurements» function execution a window appears.

  • Page 26 compare the results of different measurements performed on different documents at different times. First of all, in the CADR window open three images for which the magnetic measurements were taken. These could be the images: 1) processed and saved on a computer disk or 2) obtained as a result of three successive direct measurements or 3) any combination of previously saved and recently processed images.
  • Page 27 When the data obtained from several documents is represented in one window, it allows carrying out comparative analysis of these documents. Assessment of magnetic parameters for a fragment of the image frame (as it is described above) can be performed for each image frame.
