Description:
This manuscript describes the wide variety of optical measurement techniques for characterizing the flow in hypersonic wind tunnels. The introduction briefly describes different types of hypersonic wind tunnels, why they are used, and typical freestream conditions including fluctuating quantities. Description of these conditions defines the challenge for measurement techniques which have varying degrees of accuracy and precision, and work only in certain temperature, density and/or speed regimes. The rest of the manuscript is broken up into sections, by measurement technique. Each technique is described and then several examples are provided. The concluding chapter compares and contrasts different aspects of the measurement techniques including accuracy, precision, spatial resolution and temporal resolution.
