Stereoscopic PIV and Its Applications on Reconstruction Three-Dimensional Flow Field

Gan, L.

Abstract

Various concepts involving in the stereoscopic PIV are very briefly summarised in this section. For more details, readers are recommended to read Lavision (2007); Prasad (2000); Raffel et al. (2007). Stereoscopic PIV adopts two digital cameras viewing at the same laser illuminated plane1 from two different angles to resolve the three velocity components on the plane. Sometimes it is also called 2D3C (two-dimension three-component) PIV. The basic principle of stereoscopic PIV is similar to a pair of human eyes simultaneously observing an object to capture its movement in a plane as well as in the third direction. One major difference to the two-dimensional PIV is that the illuminated plane cannot be too thin, because the third component needs to be resolved. It should allow most of the particles to remain in the illuminated volume after the PIV t, to give valid cross-correlation signals for calculating the third component.
