From Flashlights to Brain Monitors, Diffuse Optics in Tissue
 

When you cover a flashlight with your hand, why does it glow red? Tissue absorbs blue and green light, but red light passes through. Despite the red light, you can’t see bones. This talk will describe the whys behind these common observations and explain how optics can be used to measure and monitor the brain, without using ionizing radiation.
