This article gives an overview of the background-oriented schlieren (BOS) technique, typical
applications and literature in the field. BOS is an optical density visualization technique …

We present an uncertainty quantification methodology for density estimation from
background-oriented Schlieren (BOS) measurements, in order to provide local …

This work investigates the potential of background-oriented schlieren tomography (3D-BOS)
for the temperature field reconstruction in a non-isothermal swirling jet undergoing vortex …

The understanding and predictive modeling of explosive blasts require advanced
experimental diagnostics that can provide information on local state variables with high …

We delve into the physics-informed neural reconstruction of smoke and obstacles through
sparse-view RGB videos, tackling challenges arising from limited observation of complex …

Engine component defects along the hot-gas path (HGP) of jet engines influence the density
distribution of the flow, and thus result in characteristic patterns in the exhaust jet. These …

We present an image generation methodology based on ray tracing that can be used to
render realistic images of particle image velocimetry (PIV) and background oriented …

Non-intrusive quantitative fluid density measurement methods are essential in the stratified
flow experiments. Digital imaging leads to synthetic schlieren methods in which the …

Virtual natural phenomena obtained through mathematical-physical modeling and
simulation as well as graphics emulation can meet the user's requirements for sensory …

An investigation into blade tip vortices of a sub-scale rotor under cyclic pitch conditions is
carried out. Background oriented schlieren (BOS), particle image velocimetry (PIV), and …
