The use of the Laser Doppler Velocimeter in aerodynamic facilities
Abstract
The application of the Laser Doppler Velocimeter (LDV) to flows in aerodynamic facilities is reviewed. The various components of the LDV system, i.e., optics, electronics and aerosols, which are all needed to make successful measurements are discussed. Included in the review are discussions of the various types of multidimensional systems, different types of aerosol generators and the various types of electronic systems. Included will be discussions on photon counting methods and the two-spot or dual focus systems. Some typical results which have been obtained and some on-going work will also be presented.
