Non-Intrusive measurement of a density field using the Background Oriented Schlieren(BOS) method
نویسندگان
چکیده
A method is described for measuring the density distribution in an inhomogeneous medium. This method is based upon the classical Schlieren technique, known as Background Oriented Schlieren (BOS) method. The method measures the density dependence of the refractivity through the detection of the deflecting angle of a number of light beams passing through the space to be measured. The results of some preliminary experiments are presented with detailed reference to experiment methodology and accuracy. The measurement technique is well suited to cases seeking non-intrusive robust and multi-point measurement.

Assessment and application of quantitative schlieren methods: Calibrated color schlieren and background oriented schlieren
Two quantitative schlieren methods are assessed and compared: calibrated color schlieren (CCS) and background oriented schlieren (BOS). Both methods are capable of measuring the light deflection angle in two spatial directions, and hence the projected density gradient vector field. Spatial integration using the conjugate gradient method returns the projected density field. To assess the perform...

The background-oriented schlieren (BOS) technique with the physicsbased optical flow method (OF-BOS) is developed for measuring the pressure field of a laser-induced underwater shock wave. Compared to BOS with the conventional cross-correlation method in PIV (called PIV-BOS), by using the OF-BOS, the displacement field generated by the small density gradient in water can be obtained at the spat...

Background/introduction FUS pressure field mapping is important for dosimetry, quality assurance, and other uses. Hydrophone measurements are the current standard, and are accurate but costly and slow. As a simple low-cost alternative, background-oriented schlieren (BOS) imaging of ultrasound fields has been proposed.[1] In that technique, a predetermined image (usually a grid of lines or a ran...
متن کاملAn evaluation of optical flow algorithms for background oriented schlieren imaging
The background oriented schlieren method (BOS) allows for accurate flow measurements with a simple experimental configuration. To estimate per-pixel displacement vectors between two images, BOS systems traditionally borrow window-based algorithms from particle image velocimetry. In this paper, we evaluate the performance of more recent optical flow methods in BOS settings. We also analyze the i...
