WebJan 17, 2024 · The PIVMat Toolbox for Matlab contains a set of command-line functions to import, post-process and analyse 2- and 3-components vector fields from PIV (particle image velocimetry), stereo-PIV, DIC (digital image correlation) SS (synthetic schlieren) or BOS (background-oriented schlieren) applications. WebSep 24, 2024 · II. BOS Technique. BOS works by detecting minute shifts of features in a visually textured background caused by the presence of a density gradient, which creates a refractive index change in the air (Fig. 2).A light ray from the background (a speckle) passes through a density gradient and is deflected.
