The Development and Application of Plenoptic Background Oriented Schlieren Imaging as a Flow Visualization Technique

Plenoptic background oriented schlieren imaging (plenoptic BOS) is a relatively new schlieren technique that acquires multiple line-of-sight measurements in a single snapshot, all of which can be collectively used to generate focused BOS images. Such images are used to qualitatively and quantitatively determine where density gradients are located in three-dimensional object space. This presentation will provide an overview of the plenoptic BOS technique and a brief review of recent applications and experiments using plenoptic BOS. Additionally, a discussion of future work will highlight upcoming experiments and the transition of this work towards reconstructing a three-dimensional density field using two camera plenoptic BOS.
