Abstrakt

The method of digital dynamic laser speckle photography is described. Mathematical technique of local parameters reconstruction in 3D turbulent flows is discussed and accuracy of such reconstruction is analysed. An example of flow fields reconstructed in quasi-real time operation mode are given. The flow is a convective zone above an open turbulent flame.
