We apply background-oriented schlieren (BOS) imaging with computed tomography to
reconstruct the instantaneous refractive index field of a turbulent flame in 3D. In BOS …

This paper reports a novel cone-ray model of background-oriented schlieren (BOS) imaging
that accounts for depth-of-field effects. Reconstructions of the density field performed with …

We propose a novel approach to background-oriented schlieren (BOS) tomography (BOST)
that unifies the deflection sensing and reconstruction algorithms. BOS is a 2D flow …

The estimation of time-resolved three-dimensional (3D) density fields of an underexpanded
jet at the nozzle pressure ratio of 2.42, a so-called “spatiotemporal super-resolution” was …

Axisymmetric tomography is used to extract quantitative information from line-of-sight
measurements of gas flow and combustion fields. For instance, background-oriented …

Background-oriented schlieren tomography (BOST) is effective for flow field measurement;
however, different from general computed tomography (CT), the BOST utilizes the deflection …

Quantitative flow-visualization techniques like background-oriented schlieren (BOS) are
important tools for studying complex, time-varying flows, such as high-speed jets in …

Three-dimensional background-oriented schlieren (3D-BOS) is an effective method for
reconstructing 3D density fields from optically measured data, but it has limitations in …

The development of a tomographic background oriented schlieren implementation system
utilizing up to four plenoptic cameras is presented. A systematic set of experiments was …
