Universal viewing detector Ultramag-C6 (developer LLC "VILDIS");

Mobile laboratory for researching documents, securities, banknotes, excise stamps in any conditions “Ultramag Forpost” (developed by VILDIS LLC).

The “Genetics-02” forensic unit is designed specifically for the operational control of passports, visas and other documents at stationary border control posts. Designed to equip passport control booths. Documents are controlled on a working viewing table in reflected, oblique and transmitted visible light, as well as using UV radiation (λ = 365 nm). The unit is equipped with a 2x magnifier of a large aperture. Genetika-02 can also be used for the examination of driver’s licenses, identity cards, transport and travel documents, securities, banknotes, banknotes, other printed products, including large format, with protective labels and signs.

The disadvantages of the “Genetics-02” block are the lack of infrared illumination (wavelength range from 780 to 1000 nm) and video cameras registering it, which does not allow for monitoring of image fragments made using metamer paints, as well as the use of fluorescent lamps as backlight sources, which leads to increased power consumption and reduced explantation time.

The Axium-A300 forensic unit is used for conducting an expert verification of the authenticity of various types of documents and securities simultaneously in the infrared (IR) and ultraviolet (UV) wavelength ranges. Direct radiation with a wavelength of 365 nm (UV illumination) and 850 nm (IR illumination) is used as a backlight. Sources of radiation are LEDs. The Axium-A3300 unit is equipped with a video camera with image output to the built-in LCD display. The disadvantages of Axium-A300 are an incomplete set of necessary illumination, in particular, there is no white light, as well as the use of direct incident radiation, which does not allow to control the relief parts of the control object.

The “REGULA 4305” forensic unit is intended for video spectral verification of the authenticity of documents, banknotes and other securities using the illumination of various spectral ranges (it is ultraviolet to infrared) located at different angles to the object under control. The following radiation sources are used in the unit: ultraviolet (UV 400 nm UV-A 365 nm, 6 W; UV-B 313 nm, 6 W; UV-C 254 nm, 6 W), upper white light, upper infrared light (870 nm and 940 nm), infrared bottom light (870 nm), bottom white light, coaxial white light (3M), oblique light source (flashlight), internal oblique white light source, internal infrared oblique light source (870 nm), top green light (530 nm). The REGULA 4305 block is equipped with a video camera with a video output for output to a PC. The camera is equipped with interchangeable IR cut-off and IR-pass filters. The disadvantages of the unit are the use of fluorescent lamps as UV illumination, as well as the lack of a built-in monitor, which does not allow working offline.

The Eye-D forensic unit is designed to verify the standard security features of a wide range of documents, including banknotes, passports and ID cards using visual inspection. The unit is equipped with the following radiation sources: white incident and ground light from fluorescent lamps, white oblique and coaxial light from halogen lamps, and long-wave ultraviolet illumination with a fluorescent lamp. The disadvantages of the unit are the lack of infrared illumination (wavelength range from 780 to 1000 nm) and video cameras registering it, which does not allow for monitoring of image fragments made using metamer paints, as well as the use of fluorescent lamps as backlight sources, which leads to an increase in the consumed power and reduced explantation time.

The VSC 5000A Forensic Unit is a multifunctional workstation for verifying the authenticity of banknotes, passports, visas, identification cards and other secure documents. The unit is equipped with a set of illuminators. Illuminators: top tungsten-halogen 250 W with a set of filters providing 78 sub-ranges of illumination (from 360 nm to 1000 nm), top visible / IR tungsten-halogen 2 × 50 W, bottom visible / IR tungsten-halogen 2 × 30 W, spot bottom condensed source, oblique visible / IR source 2 × 20 W (halogen) with orthogonal illumination, coaxial point source (for retroreflective studies) 1 × 24 W, UV illuminators (top: 365 nm (2 × 15 W), 313 nm (2 × 8 W), 254 nm (2 × 8 W), bottom 365 nm (2 × 8 W)). The unit is equipped with a combined color / IR 3-CCD digital camera with video output to its own monitor. The camera is equipped with visible light filters (with cutting off the short-wave or long-wave part) and 15 cutting high frequencies (530, 550, 570, 590, 610, 630, 645, 665, 695, 715, 728, 780, 830, 850, 1000 nm) Secondary adjustable by interference filter 400-1000 nm (step 3.5 nm, passband 40 nm). The disadvantages of the unit is the use of tungsten-halogen lamps, which leads to high energy consumption and reduced service life and reliability of the device.

The Ultramag-C6 universal viewing detector is designed for professional authentication of banknotes, securities, documents, excise and special stamps. It provides visualization of IR metameric, magnetic and special colors on the monitor screen (when using additional peripheral equipment). The successful design of the backlight unit provides effective control of UV-luminescence of protective paints even in bright ambient light. The detector is equipped with powerful (6 W) lamps (up to 3 pieces) UV 365 nm, UV 254 nm and white glow in any combination. The detector is equipped with a built-in monitor, and also has a composite video output for connecting to a computer or external monitor. The disadvantage of this unit is the use of fluorescent lamps as sources of illumination, which leads to increased power consumption and reduced life.

In terms of functionality and design, the closest to the device is the Ultramag Outpost analogue, therefore it is taken as a prototype.

Ultramag Forpost, a mobile laboratory for researching documents, securities, banknotes, and excise stamps under any conditions, is designed to analyze the security features and structure of documents under any conditions. The laboratory includes: a white lamp 9 W, built-in UV lamps 254/365 2 × 6 W, side LED illuminators, a spectral camera with various backlights (white light, UV 375 nm, blue-green light 502 nm, flashing 850/940 nm , side IR 850 nm, side white, powerful 980 nm), a black and white IR camera with 880 nm backlight and a set of filters (IR transparent, visible, IR delay). Information is output to the built-in or external monitor. The disadvantages of Ultramag Outpost is the use of halogen lamps, which leads to increased energy consumption and reduced reliability.

The purpose of the proposed technical solution is to create a device for light-optical verification of documents "Genetics-09".

This goal is achieved by the fact that the device is arranged in a single housing, all illuminators are semiconductor emitters, due to this, the power consumption is significantly reduced and the life of the illuminators is increased and it allows monitoring the signs of authenticity of documents and identifying traces of unauthorized influences.

The device using transmitted, reflected and oblique visible radiation allows you to:

- control the quality of watermarks of paper media;

- identify traces of rubbing and erasing;

- determine the integrity of the stamp and relief seals;

- identify traces of mechanical stress and pressure of the writing instrument on the sheet.

The device using UV radiation allows you to identify protective labels of luminescent dyes, signs of substitution of document sheets by the difference in the luminescence glow of paper bleaches, residual ink, glue, traces of washing and etching reagents.

In the upper part of the device there is a monitor that receives a video signal from a video camera integrated in the upper case cover. The camcorder allows you to register images obtained under infrared illumination.

The device using secondary reflected infrared radiation allows you to:

- identify supplements and corrections made by writing material, one-color with the original material, but with a different level of absorption of infrared radiation from it;

- read fragments drenched in ink or a paste of ballpoint pens;

- provides recognition of optically dense parts on the back of the sheet and the next page, deposited with materials that absorb infrared radiation. The use of two spectral ranges of infrared radiation (830 nm and 940 nm) allows monitoring the presence and distribution of labels of certain types of special dyes used for protection against fakes, the absorption level of which is different for these ranges of infrared radiation.

The backlight modes are controlled using the keyboard located on the front edge of the desktop.

On the back of the desktop are connectors that can connect a microscope that allows you to view small details and microtext in documents, as well as a video magnifier for controlling documents in infrared illuminations, and all these devices are electrically connected, the video signal from which is transmitted to the device’s built-in monitor.

A video magnifier using secondary luminescent radiation of the far red and infrared ranges provides:

- identification of supplements and corrections made by single-color dyes that differ in yield and luminescence spectrum;

- identification of traces of the effects of washing and etching compounds with the ability to read the destroyed inscriptions, seals and stamps;

- identification of differences in the effects of dyes, writing materials and other substances on paper;

- identification and reading of luminescent inscriptions printed on the back of the sheets with ballpoint pen pastes, ink, ink inks and colored ink;

Secondary reflected infrared radiation from a source of oblique infrared radiation provides for the identification of relief fragments on the sheet plane — subtypes, erasers, and traces of pressure of the writing instrument.

The video microscope allows you to view small details of the image with high magnification (25 times) on the built-in display, and for easy viewing, the microscope is equipped with a built-in white backlight.

On the back wall of the device case there is a slot 10 mm high for the convenience of moving documents.

The location of radiation sources, optical elements and their characteristics ensure high quality and efficiency of documents carried out on the research device.

The device allows you to connect external devices for additional control of documents, including video devices.

To output a video signal from the device, it has a corresponding video output, which can be used to connect to external monitors or video recorders.
