Professor Scott C. BunceThe NewScientist article Invention: Infrared lie detector said
Although security services the world over have used lie detectors to lock many people up over the years, they are not very reliable.
Scott Bunce, at Drexel University’s College of Medicine in Philadelphia, thinks a better solution is to send near-infrared light through the scalp and skull into the brain and see how much is reflected back. And he has designed a special headband that does just that.
The amount of reflected light is dependent on the levels of oxygen in the blood, which in turn depends on how active the brain is at that point.
This, he says, gives a detailed picture of real-time activity within the brain that can be used to determine whether the subject is lying. The technique is both cheaper and easier to apply than fMRI and gives a higher resolution than an EEG.
