Seedless Velocimetry Measurements by Schlieren Image Velocimetry

AIAA Journal, 2011
Schlieren optical systems have been used to perform velocity measurements in refractive turbulent flows using particle image velocimetry algorithms. This schlieren image velocimetry (schlieren "particle image velocimetry") technique makes use of naturally occurring refractive turbulent eddies in a flow as virtual "seed particles" upon which velocimetry

Thermal Image Velocimetry

Boundary-Layer Meteorology, 2013
A method for measuring the two-dimensional distribution of wind velocity vectors near a surface exposed to solar radiation, by tracking brightness temperature images instead of particle images, is proposed. It is based on time-sequential thermography with the algorithm used for particle image velocimetry. This thermal image velocimetry (TIV) was tested

Digital image velocimetry

Applied Optics, 1988
A new technique, digital image velocimetry, is proposed for measurement of instantaneous velocity fields of time dependent flows. A time sequence of single-exposure images of seed particles are captured with a high speed camera, and the sampled images are then digitized on an image processor, enhanced, and superposed to construct a multiple-exposure ...
