Abstract [sv]

In-line holography, where the reference beam coincides with the beam that is scattered against the droplets, has been found to be a versatile and simple experimental method for spray diagnostics using holography. Such an experiment was setup and a water spray was studied and holograms of high quality was obtained using a CCD-camera.

The holograms were analysed with Wavelet analysis, implemented as a Matlab program. It was found that the droplets’s size and position could be reconstructed with reasonable accuracy. Future work will focus on a dynamic analysis program that dynamically adapts the wavelet analysis parameters to each detected droplet.

Key words: spray diagnostics, laser diagnostics, holography, image processing, wavelet analysis
