Particle sizing and spray analysis; Proceedings of the Meeting, San Diego, CA, August 21, 1985

Papers are presented on obtaining particle velocity and displacement distributions from double-exposure holograms using optical and digital processing, the accuracy of measurement in coherent imaging of particulates in a three-dimensional sample, and geometric properties of nondifferentiable contours. Also considered are filtering effects in far-field in-line holography and in diffraction pattern analysis, particle sizing interferometer nephelometry, the characterization of suspended particulates on multicomponent systems using polarization intensity ratio and pointer beam techniques, and the effects of nonspherical drops on a phase Doppler spray analyzer. Other topics include extension of the phase/Doppler particle analyzer to submicron particle measurements, a performance comparison of two interferometric droplet sizing techniques, size and shape variations of liquid droplets deduced from morphology-dependent resonances in fluorescence spectra, and a flexible high-speed digital image processing system.
