Schlieren measuring process detects changes in turbulent atmospheric flow, aerodynamic, chemical processing and environmental pollution

摘要

A Schlieren measuring process monitors the three-dimensional distribution of density and material of phase objects which interrupt radiated patterns. The resultant signals are visualized, and use in measurement, regulation, control and test processes. In the process, light is emitted from a structure, self-illuminating source or a light-scattering background, and passes through a phase substance along a main axis. Light is scattered in two directions transverse to the main axis. Small sections of the transverse images are compared with each other by super-imposition.
