Abstract

Liquid spray is mainly made up of tiny spherical droplets fully atomized and small non-spherical ones which may be deformed or sheared by liquid injection.<BR>This paper presents the technique of phase-shifting digital holography for measuring ellipsoidal objects distributed in 3D space, objects which are the typical non-spherical ones. Hough transform is employed for detecting the minor and major axes for each ellipsoidal object on reconstructed images. Numerical simulated results show that the number of objects is successfully counted and thee minor and major axes are measured with accuracy using the present method.
