Author Affiliations +
We present a novel technique for 3D-tracking micro- and nanoparticles with original lens-free dark-field holographic microscope. Combining lens-free and dark-field microscopy principles this technique allows for high accuracy localization of micro- and nanoparticles using single hologram acquired with compact setup built with minimal use of optical components. In this paper, we present technique of particles localization, experimental setup, technique of digital correction of spherical aberration, results of simulation and experimental data.
