Combination of cross correlation method and stereoscopic colour photographs are appliied to obtain 3-dimensional velocity components.
Measuring plane is perpendicular to the uniform flow direction and the plane is lighted by slightly thicker red and green slit light sheet, one of which has a short time lag Δt against the other.
The colour photographs are seperated by 3-colour image processing device for the data of cross corelation method.
Two kind of flow fields are measured and reasonable results were obtained.
