The document discusses computational plenoptic imaging and Schlieren imaging. It covers topics like background oriented schlieren (BOS), optical setups for Schlieren imaging including high-frequency backgrounds, transparent refractive objects, and camera arrays. Applications of Schlieren imaging like aeronautics and ballistics are also mentioned. Oriented Schlieren imaging using light fields is described as optical encoding and computational processing of transparent refractive objects using light field probes and cameras.
