A description is given of a laser system used to produce interferograms of a large centrifugal compressor, powered by an industrial gas turbine engine with a dominant system response at 168Hz. The results demonstrate a travelling wave generated within the feed pipe to the compressor. Finally the description of a potential real time double pulse systeu is presented.
