In this image a flat-plate delta wing is approaching a laser sheet shining through lenses below. The wing was mounted in a water tank and is being towed at approximately 1 m/s. The water has been seeded with tiny reflective particles so that as the wing passes through the laser sheet, a camera can film the motion of these particles and later process them to determine the velocity field of the trailing wake. This is called particle image velocimetry, or PIV. Understanding the behaviour of the wake can shed light on delta wing performance in other situations.
