| Abstract: | The principles and the experiment for temperature and OH concentration fields measurement by LIPF is mentioned in this paper. With a tunable KrF excimer laser, the fluorescence of OH was gotin a methane-air flame at the pressure of atmosphere and the structures of the spectrum were analyzed. Theinstantaneous temperature in the flame was also given out by LIPF, the relative error is less than 3%. Thefluorescence images of OH shows the direct images of densities and the tempetature fields in quality. |
