In order to optimize the efficiency of compressors and gas turbines, flow measurements are required for investigating important flow phenomena such as the development of vortices. For this purpose, optical measurement tools were developed capturing velocity flow fields non-intrusively. However, those systems are often designed for the use in laboratory under stable environment conditions and require a high expertise. In industrial environments, high temperatures up to several 100 °C can occur e. g. at turbo...
