<title>High-speed photography and imaging spectroscopy for radiation behind strong shock waves in air</title>

Abstract

This paper describes some applications of image-intensified CCD camera systems to high-speed photography of radiation behind strong shock waves in low-density air to get two- dimensional images of total radiation and spatial-resolved spectra in shock tube experiments. The resultant images of total radiation are shown for incident shock waves and shock reflections on a wedge. Some two-dimensional flow features are clarified for these shock wave phenomena. A couple of CCD camera systems are applied to simultaneous observation of the total radiation and its spatial-resolved spectra along the tube axis, giving us a clear understanding for the spatial relationship between them.
