Reakce lidského těla při lhaní zaznamenaná polygrafem a termokamerou

Abstract

The bachelor thesis deals with the investigation of the human body reactions during lying recorded by a polygraph and a thermal imaging camera. The introductory theoretical part clarifies the basic principles of the used devices, the physical basics of the thermal imaging camera, i.e. a description of electromagnetic radiation and related physical laws or a blackbody, and physiological changes detected by the polygraph (i.e. respiratory rate, blood pressure, heart rate, skin resistance and activity). It also deals with the constructions of the used devices or the factors influencing the measurement. The following practical part is dedicated to the used devices, experimental measurement and its evaluation. The aim of the thesis is to compare the reaction of the human body during lying, based on the results from the polygraph and the thermal imaging camera during scanning this person.
