Assessment and application of quantitative schlieren methods: Calibrated color schlieren and background oriented schlieren

Experiments in Fluids, 2003
Two quantitative schlieren methods are assessed and compared: calibrated color schlieren (CCS) and back- ground 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.

Interferometry with schlieren microscopy

Applied Optics, 1977
It is demonstrated theoretically that if the stop in a schlieren system is no larger than the central maximum of the empty field Airy disk at the stop location, the system will behave as an interferometer for objects much smaller than the empty field. Interferograms produced by such a system are shown.

Schlieren and BOS velocimetry of a round turbulent helium jet in air [PDF]

Optics and Lasers in Engineering, 2022
Seedless velocimetry is gaining interest in many industrial and research applications. We report on a comparative study of time-resolved optical velocimetry using traditional, mirror-type knife-edge schlieren optics versus Background-Oriented Schlieren ...

The spread of breathing air from wind instruments and singers using schlieren techniques

Indoor Air, 2021
In this article, the spread of breathing air when playing wind instruments and singing was investigated and visualized using two methods: (1) schlieren imaging with a schlieren mirror and (2) background-oriented schlieren (BOS).

Qualitative and quantitative schlieren optical measurement of the human thermal plume

Indoor Air, 2020
A new large-field, high-sensitivity, single-mirror coincident schlieren optical instrument has been installed at the Bauhaus-University Weimar for the purpose of indoor-air research.

Development of a Self-Aligned Compact Focusing Schlieren System for NASA Test Facilities

AIAA SCITECH 2022 Forum, 2022
A novel compact, inherently self-aligned focusing schlieren system is presented for use in experiments that require flow visualization. Unlike existing focusing schlieren systems that require a separate, and precisely aligned, source grid and cutoff grid ...

Qualitative evaluation of the flow supplied by personalized ventilation using schlieren imaging and thermography

Building and Environment, 2020
Personalized ventilation (PV) is a mean of delivering conditioned outdoor air into the breathing zone of the occupants. This study aims to qualitatively investigate the personalized flows using two methods of visualization: (1) schlieren imaging using a ...
