METHOD AND DEVICE FOR DETECTING HIDDEN SUBSTANCES

摘要

The invention relates to examining substances with the aid of electromagnetic fields and can be used in stationary and mobile control systems for detecting and identifying different substances. The positive result is attainable by the inventive method consisting in measuring and recording information on spatial-frequency features of a detectable, identifiable substance, and, afterwards, using said information, in generating and applying a local non adiabatic electromagnetic field fluctuation carrying said information and in recording the response of the field by measuring the non-uniformity characteristics in the polarisation of the field local fluctuation and low-frequency beats caused by the interaction of substances in said area with said field and in drawing a conclusion about the presence of a detectable hidden substance amongst said substances by comparing the obtained characteristics with those of the detectable substance.
