The successful use of a pulsed laser and 35mm streak drum camera in the recording of gas shock phenomena in shock and detonation tubes is demonstrated and discussed. One application will show a sequence of laser sheet images of the shock-induced mixing of gases of different density (one seeded). A second will show shadowgraph image capture of the fusing of detonation waves from multi-point ignition of an oxy-acetylene gas mixture. Also a novel technique combining shadowgraphy and laser sheet imaging will be presented and discussed. This allows visualisation in experiments of both detonation waves and subsequent shock-induced turbulent mixing. The limitations and relative merits of photographic film and CCD camera imaging will be briefly discussed. A video sequence shows the capability of recording 50 images on a single shock tube experiment.
