Abstract

High speed Schlieren photography is a reliable means of visualizing small changes of refractive index resulting from density differences within a transparent media. Schlieren techniques are frequently used for investigating the aerodynamics of high velocity projectiles to confirm the formation of shock waves on leading edge surfaces so that optimum design performance can be achieved. Traditionally this type of investigation would have been undertaken using film cameras, however, improvements in image quality provided by the rapid development of intensified silicon based sensors and associated electronics has offered a reliable alternative, without the inherent difficulties in quantitative data extraction. The development of a high resolution sixteen image electronic camera system provides the researcher with versatile recording system that can be used to capture detailed image sequences at framing rates up to two hundred million pictures per second. The number of information points is maintained, irrespective of framing rate, making it ideal for recording the complexity of detail available from these sensitive Schlieren techniques. The high resolution images, which are displayed within twenty seconds of capture, flexibility of operation, and comprehensive analysis software provide fast reliable access to experimental data.
