Engineers at NASA's Langley Research Center in Hampton, Virginia, used lasers inside the 14- by 22-Foot Subsonic Tunnel to map how air flows over a Boeing Blended Wing Body (BWB) model – a greener, quieter airplane design under development.

The name for the technique is called .

If you look closely you can see the light bouncing off tracer particles. Cameras record the movement of those particles as the laser light pulses across the . This allows researchers to accurately measure the flow over the model once the images are processed. A smoother flow over the wing means less fuel will be needed to power the aircraft.
