This is a comprehensive, critical, and pedagogical review of volumetric emission
tomography for combustion processes. Many flames that are of interest to scientists and …

Tomographic background oriented Schlieren (Tomo-BOS) imaging measures density or
temperature fields in three dimensions using multiple camera BOS projections, and is …

This paper describes the development and use of background-oriented schlieren imaging of
a full-scale supersonic jet in flight. A series of flight tests was performed in April 2011 …

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 …

We report a new workflow for background-oriented schlieren (BOS), termed “physics-
informed BOS,” to extract density, velocity, and pressure fields from a pair of reference and …

Optical flow provides an opportunity to elevate the resolution and sensitivity of deflection
sensing in background-oriented schlieren (BOS). Despite extensive relevant literature within …

The main purpose of this work is to propose a new method to evaluate the concentration
distribution of the hydrogen jet by using a He–Ne laser through the jet. This research …

Mid-infrared laser absorption imaging of flame temperature and species concentration is
expanded to three dimensions with linear tomographic methods using Tikhonov …

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 …

This paper investigates the application of a 3D density reconstruction from a limited number
of background-oriented schlieren (BOS) images as recently proposed in Nicolas et al.(Exp …
