Pagination or Media Count:
Various laser systems being used for tests in laboratories and environmental facilities at AEDC are described. These systems include the laser Doppler velocimeter used for flow field diagnostics, laser holography used for flow field visualization and particle studies, laser spark generation used to measure velocities in high speed flows, laser photography used for visualization during ablation tests, and vapor screen systems used to visualize flow patterns around models. Schematics of the systems are given, and some results from tests which have utilized laser instrumentation are presented.
