Modern speckle photography based on the computer-aided evaluation of speckle patterns extends the methods of optical flow visualization and diagnostics, and it allows the quantitative derivation of a two dimensional map of the angles of deflection experienced by light when passing through a flow under study. Such a map may be used for the tomographic reconstruction of 3D density (or temperature) fields in both laminar and turbulent flows.
