More Information
Summary:Provided is an optical sensor directed into a combustion chamber is used to selectively sense a predefined spectral range of an optical spectrum for different light paths running through the combustion chamber to measure a gas temperature distribution in the combustion chamber. A spectral intensity is determined for each spectral range and associated with an item of light path information which identifies the light path in question. The spectral intensities determined and and the associated items of light path information are fed as input data to a machine learning routine which is trained to reproduce spatially resolved training temperature distributions. Output data from the machine learning routine are then output as the gas temperature distribution.
