Abstract A high speed, high resolution spectrum measurement system was built to diagnose the high temperature combustion gas flow. The theoretical model of the spectral transmittance measurement of high temperature combustion gas flow was also established. A stable tungsten lamp was used as an on-site standard to measure the transmittance of a typical position of the gas flow. Preliminary experiments showed that the spectral transmittance of the combustion gas flow was about 0.9 in the spectral range 500~800 nm but without strong spectral correlation.
