For decades, scientists have used near-infrared light to study the brain in a noninvasive way. This optical technique, known as "fNIRS" (short for "functional near-infrared spectroscopy"), measures ...
Members can download this article in PDF format. Light sensors detect the presence or absence of light, and the intensity of that light. These sensors then convert light energy into an electrical ...
In case you thought that cameras, LiDAR, infrared sensors, and the like weren’t enough for Big Brother to track you, researchers from Carnegie Mellon University have found a way to track human ...
