Holografinės interferometrijos metodų taikymo kriminalistiniuose tyrimuose galimybės
Abstract
Increasing crime rates and making various nature of offenses, criminal investigation under
modern conditions require ever more sophisticated and spectacular forensic investigation tools and
techniques. One the way can improve these issues is the practical application of achievements in the
holography. Holography as a research method used in various scientific and technical fields, where the
main role of a light waves of diffraction and interference. In this paper presents the major holography,
as one of the forensic image capture methods, the differences and advantages compared with forensics
photography method and application opportunities of forensics research. In the article to get there its
purpose - is theoretically and experimentally based on one of the practical applications of holography
directions - holographic interferometry, potential as a research method for preventing, identifying and
testing for public security by dangerous acts. Implementing this objective must be to meet these
challenges: to explore the holographic interferometry as a research methods, concept and physical
meaning, analysis of possible ways of testing the evidence, to analyze the evidence in the investigation
of possible ways, the propose for realizing of technical measures discussed ways of testing, to evaluate
these forthcoming results. Examined holographic interferometry to the study design and the physical
meaning of the concept, analysed potential available research methods of the evidence (twoexposition,
time-average, real-time, terrain contour formation) and their operating principles.
Presented generated holographic stand flowchart and major items of equipment. In the experimental
paragraph to give research the results in the field of document investigation. Studies have been
performed in determining the monetary unit Lithuanian litas banknote counterfeiting capabilities and
are perform a qualitative and quantitative analysis of the results. Another study of personal of
document investigation has been made as to the authenticity of driver licenses for using of the
holographic system PRISM. The obtained results suggest that the application of the methodology
time-average can be authenticated quality and counterfeit documents. In the article drew attention to
other possibilities of using holography in the criminalistic practice. An experiment confirming the identification of crystals in high-value opportunities.
