Abstract : New laser-based diagnostic techniques offer considerable promise for measurements in hypersonic flows. In this paper , we overview optical techniques such as Rayleigh and Raman scattering, laser-induced fluorescence, electron beam fluorescence, coherent anti-Stokes Raman scattering and diode laser absorption. These methods have unique capabilities for nonintrusive measurements of flowfield parameters such as temperature, density, species concentration and velocity. The applicability of these techniques for the study of hypersonic flows is also presented.
