Abstract

Using intensity gradient based or sparsity based focusmetrics, the ability to accurately localise the 3D position of a small object in a digital holographic reconstruction of a large field of view is hindered in the presence of multiple nearby objects. A more accurate alternative method for 3D localisation, based on evaluation of the complex reconstructed volume, is proposed.Simulations and experimental data demonstrate a reduction in depth positional error for single objects anda notably improved axial resolution of multiple objectsin close proximity.
