eyeBOS is a new powerful tool for Background Oriented Schlieren applications which uses an optical flow algorithm embedded in a GPU card. Within eyeMOTION, the eyeBOS plugin allows to see the displacement of a random dot pattern to reveal the refractive index gradients in real time or instant post-processing !
Description
BOS is an optical density visualization technique, belonging to the same family as schlieren photography, shadowgraphy or interferometry. Schlieren imaging is based on the deflection of light rays passing through refractive index gradients in a transparent medium. In contrast to this, eyeBOS uses optical flow correlation technic on a background random dot pattern to quantitatively characterize compressible and thermal flows with good spatial and temporal resolution.
Features

- Real time processing with live view results
- 1 displacement value per pixel
- Intuitive user interface
- Low data storage requirements
- Low energy consumption
Applications
- Combustion analysis
- Gas flows
- Thermal analysis
- etc.
