New Fingerprint Technology DevelopedLos Alamos National Laboratory scientists are using a new technique to see fingerprints on surfaces that typically make them invisible. The method uses a technology called mini-X-ray fluorescence to detect chemical elements in fingerprints without altering them, said Christopher Worley, a scientist on the project. "The conventional methods are meant to bring out fingerprint patterns with regular light and they have to treat those with powder, which alters them," Worley said. "with this you do not have to alter it or treat it at all. We can determine the elements in a fingerprint and get a pattern at the same time. "The technology focuses a tight beam of X-rays on surfaces with fingerprints and creates a computer picture out of those scans. The equipment costs about $ 175,000. For Big Labs, The Method Could Be a Great Way To Bring Out Prints That Can't Be Seen Any Other Way, Said VahiD Majidi, Another Lab Scientist. "The Technique Fills a Unique Niche," Majidi said. "These are prints that would otherwise be useless. If you have prints on a dark surface, for example, they really do not develop well using normal techniques. If you have prints from an adolescent or child, the chemicals in the fingertips are different and do not stick around long enough for traditional methods. "The new method might also be able to tell if the person that left them handled certain types of bomb-making materials, said George Havrilla, another lab scientist." This IS A New Approach To FingerPrint Visualization, "HAVRILLA SAID." We're Lifting Prints, But Instead of Looking At The Finger's Natural Oils and Organic Residues We '
re looking at elemental features left behind. "The technology for scanning the prints is widely available. What's new is the method the lab has created to see them which includes computer software and ways of manipulating the machinery, Worley said. But the technique isn ' t for everyone. "We've already had some negative comments on it," Havrilla said with a laugh. "One reviewer told us it's just not practical. But the goal of our work was to demonstrate that it was feasible to see these things "(Agencies) scientists in the American Los Aramos National Laboratory adopted a new technique, and it was observed that the fingerprints that were difficult to see on the surface of the object. Scientists participating in the research project Christopher Walle said, The method uses a "micro-x-ray bundle fluorescence technology", which can detect the chemical components carried by the fingerprint, but does not change the preservation state of the fingerprint. Walle said: "The traditional method is to display the fingerprint through conventional light Moreover, this will change the fingerprint preservation status by means of a powder such as powder. With this new method, you don't have to change or process your fingerprint, we can measure the chemical composition contained in the fingerprint while getting a fingerprint pattern. "This technique leaves a bundled X-ray to the surface of the fingerprints, and creates a computer image according to the scan results. This set of equipment is 1.75 million US dollars. Another scientist of the laboratory Wahid Majid Said, for those big labs, this is the best way to get blots that can be seen in other ways. Majid said: "This technology fills an airline. If there is no such technology, some blots will become meaningless. For example, if it is a fingerprint on a dark surface, ordinary skill does not detect them accurately; if it is a teen or child's fingerprint, their fingertips have different chemical components (and adults), and these fingerprints The time attached to the surface of the object is not suitable for use of traditional analytical methods. "Another scientist of the laboratory said George Haoflo said that this new technology may also detect whether the fingerprint owner touches some type of bomb manufacturing materials. Haoflo said:" This is clear A new way to show fingerprints. We look for blotting, no longer just observe the fat and residual organic matter secreted by the finger, but focus on the special chemical ingredients behind it. "Walle pointed out that the technology of scanning prostitutes is currently widely adopted. Innovation of this new fingerprint detection method in the laboratory is that it includes computer software technology and machine operation methods. But this technology is not everyone All. Haoflo said: "We have received some negative comments. A critics say that it is not practical. But our work is to prove that this technique is practical. "(China Daily Website Translation)
