This paper describes an experimental application of planar droplet sizing technique, applied to the study of spray impingement onto a hot plate. By employing interferometric laser imaging for droplet sizing (ILIDS), including analysis of the out-of-focus droplet images, we can measure the instantaneous spatial distribution of droplet size. The experimental results showed that both arithmetic and Sauter mean diameters near the hot plate increased in contrast to the regions far from the plate. The measured droplet behavior in the vicinity of the hot plate demonstrated the important differences in the velocity and direction before and after impinging. i.e. the droplets moved upstream due to impingement reversal at the hot plate.
