EXPLOSIVES DETECTION SYSTEM BASED ON SPECTROSCOPY METHOD OF MULTIBROKEN TOTAL INTERNAL REFLECTION (MBTIR) WITHIN BIOMETRIC IDENTIFICATION PROCEDURE

摘要

FIELD: physics, measurement.;SUBSTANCE: invention refers to measurement technology. The system consists of personal identification system representing system of biometric information comparison including optical scanner with MBTIR element mounted on its working surface, and systems of explosives (E) detecting and identification including analyser with IR source. Besides the system comprises signal processing unit and alarm indicator. MBTIR element represents parallel-sided plate with bevel side faces made of optical material with refraction index exceeding that of the material used for optical scanner prism. The plate material transmits radiation within the range corresponding to absorption spectra of identified substances, as well as radiation with which the biometric scanner operates.;EFFECT: higher reliability and downsizing of system.;3 cl, 4 dwg
