Laser Diagnostics in Fluid Mechanics

B. S. Rinkevichius
Moscow Power Engineering Institute, Moscow, Russia

Beschreibung

This monograph is intended for engineers and scientists concerned with laser-aided investigations, as well as students and post-graduate students. It describes the methods of laser diagnostics of fluid and gasws that are currently finding wide applications in aero- and hydrodynamic studies, power engineering, space and aircraft industries, chemical engineering, metallurgy, biology, environemental sciences, and much more. Chapters range from fundamental laws of optics as they related to laser beams, through laser radiation, scattering, to laser diagnostics methods.
