From a distance, a beam is directed at a person to measure their psychological and physiological response through the skin. The United States is developing a type of remote lie detector device.

The lie detector device is currently widely used in the United States. The individual being tested is equipped with sensors to monitor signs of deception. |
The U.S. Department of Defense (DoD) has recently announced plans to develop a lie detector machine.
This machine can be used without the subject knowing they are being tested.
The Remote Personnel Assessment (RPA) device will also be employed to accurately identify locations where soldiers are hiding on the battlefield.
Furthermore, the device can detect signs of stress that may indicate an individual is a terrorist or a suicide bomber.
In a call for proposals on the DoD website regarding this plan, contractors have until January 13 to submit their development options for the RPA.
The RPA can utilize short-wave or laser beams that react to human skin to evaluate various physiological parameters without the need for wires or physical contact with the skin.

In the near future, one could simply stand at a distance, direct a beam at a person, and determine if they are exhibiting signs of deception. |
The device will project a beam that “moves and requires no cooperation from the subject,” according to the DoD, and it will rely on reaction signs to deduce impulses, respiratory rates, and changes in electrical conductivity, known as “skin stimulation response.”
The DoD asserts that the RPA will identify the physiological state of the subject. For instance, if the subject feels stressed or confused, it indicates they are lying. Thus, the RPA will also be used as a remote lie detector during criminal investigations.
However, discovering ways to implement the DoD’s announcements will present many practical challenges… Robert Prance, an electrical engineer and expert in “non-invasive” sensors from the University of Sussex, UK, stated: “It is possible to capture the respiratory rate using infrared laser by sensing vibrations in the chest. But measuring a pulse through clothing is a significant challenge.”
If the RPA is indeed produced, it may spark controversy.
A remote lie detection device will face greater difficulties than conventional heart rate monitoring devices. Steve Wright, an expert from Leeds Metropolitan University, UK, warns that the RPA could always evoke a chilling sensation among individuals in everyday life.
