EVALUATION OF PULSED LASER HOLOGRAMS OF SPRAY DROPLETS BY APPLYING DIGITAL IMAGE PROCESSING

Get access DOI: 10.1615/IHTC9.2840
pages 187-192

Sinopsis

The evaluation of pulsed laser holograms has been improved substantially by using digital image processing. Here, two computer aided procedures to evaluate single and double pulsed laser holograms of spray droplets are presented. By using these techniques implemented on a personal computer, it is possible to apply more efficient droplet focussing and classifying criteria throughout the whole evaluation process. The time dedicated to the evaluation is drastically reduced and the accuracy in drop sizing is improved by about one order of magnitude compared with other hologram evaluation methods.
