In order to obtain small density variations in flow field, an image processing system for analyzing interferograms is developed. A Mach-Zehnder interferometer is used for visualization of flow field, and images are directly taken by a CCD-camera. The image is displayed immediately after each shot, and processed on a personal computer. Using this system, weak shock waves in carbon dioxide are observed for incident shock Mach number 1.02 to 1.06 and initial pressure 147 to 196 kPa. This paper presents the detail of density distribution of flow fields, which are generated by weak shock waves, passing over a hemicylinder and reflecting from wedges, in carbon dioxide.
