Development of Pulse-Burst Laser Source and Digital Image Processing for Measurements of High-Speed, Time-Evolving Flow

Abstract

This AASERT Grant on the development of a "Pulse-Burst Laser Source and Digital Image Processing for Measurements of High-Speed, Time evolving Flow" was originally paired with Grant #F49620-92-J-021V entitled, "Quantitative Imaging of Time-Evolving Structure in Supersonic and Hypersonic Flows." That grant ended in December 1994. The students have more recently been working in conjunction on the development of diagnostics in association with "Shock Propagation and Supersonic Drag in Low Temperature Plasmas (#F49620-97-1-0497) which began June 1, 1997. Major accomplishments achieved under this AASERT Grant were the fabrication of a cavity-locked, injection-seeded Ti:Sapphire Laser and the demonstration of UV filtered Rayleigh scattering imaging in a supersonic jet, the fabrication/characterization of a narrow passband transmission filter, and the development of a new concept for a line imaging Raman spectrometer for flow field, combustion, and plasma diagnostics.
