Analysis and numerical correction of aberration in interferometric particle imaging

Abstract

Interferometric Particle Imaging (IPI) is a convenient technique to determine the size and the shape of irregular rough particles. But it requires the analysis and the correction of all sources of noise that can modify the interferometric images and thus the reconstruction procedure. This study describes the role of spherical aberration in IPI. It proposes a numerical model to predict IPI images in presence of this aberration and a method to correct his effect.
