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.
