  • Influence of exciting laser sheet intensity distribution on the fluorescence intensity distribution in a Planar Laser-induced Fluorescence(PLIF) experiment was analyzed. Based on cylindrical lens array, a laser sheet shaping system was designed. According to the requirement of PLIF, several parameters were optimized with ray tracing method. The laser beam shaping experiment system was established and applied to the PLIF experiment for dye laser beam shaping and acquiring smoothing laser sheet with the nonuniformity no more than 4%. With the uniformity laser sheet beam, PLIF was applied to the measurement of fluorescence imaging of OH in alcohol flame and CH4/air premixed combustion.
