Structured light plethysmography
Ok kiddo, have you ever seen a doctor put a little clip on your finger to measure how much oxygen is in your blood? That's called a pulse oximeter. Well, structured light plethysmography is kind of like that!
Basically, scientists use special cameras and lights to take pictures of your face and measure how much blood is flowing through your blood vessels, just like a pulse oximeter measures the oxygen in your blood. They shine a structured pattern of light on your skin, and then watch how the light bounces back off your face.
The way the light bounces off your skin tells the scientists how much blood is flowing through your skin, and how fast it's going. They can use this information to study things like how your blood vessels change when you get excited or scared, or how different medical treatments affect your blood flow.
While it might look a little funny to have cameras and lights pointed at your face, structured light plethysmography is a very useful tool that helps doctors and scientists learn more about how our bodies work.
