Evaluation of the psychoemotional human state via terahertz image of the face

An approach to evaluation of the psychoemotional human state is discussed. The approach is based on an analysis of simultaneously registering infrared (IR) and terahertz (THz) emissions of the human body. Simultaneous registration of IR - THz images of a human face and psycho physiological indicators is carried out in situations of physical stress (short-term intensive physical exercise - functional squat test), electrical stimulation and informational stress (cognitive load - simple arithmetic mental calculations). Using the special analysis of IR - THz images, subjects can be divided into classes according to the type of reaction under stressful conditions.
