The war against terrorism requires advanced forensic technology. In this regard, it is important to develop perfect lie detectors, aka printing. Until now, any detector can be fooled. However, not so long ago there were fundamentally new lie detectors.
This model responds to temperature changes around the eyes. This is one of the first devices that read the psychophysical data without direct contact with the human body.
Moreover, the data are processed instantly and expertise does not require the presence of psychophysiology, as is the case with traditional lie detectors.
The principle of operation is based on the fact that when a person experiences psychological discomfort - is lying or disingenuous - he has increased intraocular pressure, there is a rush of blood to the eyeballs, because of which the temperature rises periocular area.
