Planar Image Particle Analyzer for Whole Field Spray Applications

Abstract

The purpose of this work is to develop a whole field measurement technique that is capable of simultaneously sizing multiple transparent droplets on a plane from scattered light features that are independent of laser beam intensity and obscuration. Light scattered by reflection and refraction from droplets immersed in a laser sheet is recorded holographically to yield the smallest possible probe volume and correspondingly largest number density. Last year we reported droplet size results obtained with conventional optical holography and some preliminary results of different objects obtained with digital holography. This year we report the first droplet size results obtained with digital holography.
