Background oriented Schlieren using celestial objects |
| 摘要 |
The present invention is a system and method of visualizing fluid flow around an object, such as an aircraft or wind turbine, by aligning the object between an imaging system and a celestial object having a speckled background, taking images, and comparing those images to obtain fluid flow visualization. |

1. A system for visualizing fluid flow around an object in operation, comprising:
an imaging system focused on a celestial body having a speckled background, wherein the fluid flow comprises a location between the speckled background and the imaging system; and, an image processing system capable of comparing an image of the speckled background with no fluid flow to one or more images of the fluid flow in front of the speckled background by obtaining a measurement of movement of pixel features in the speckled background between the images, created by light refracted by the fluid flow. |
