Paper Abstract

In this work we present a different method to reduce shot noise in phase imaging from digital holograms. An averaging process of phase images reconstructed with different reconstruction algorithms of the complex amplitude of a phase object in digital holographic microscopy. We obtain an improved phase image reaching a 29% of shot noise reduction. We use a single object complex amplitude that is needed to perform our proposal. Also show the corresponding simulations and experimental results. As phase sample test we used a micro-thin film step surface made at home of 100 nm high of TiO2 on a glass substrate of 4.7 mm thickness, our system was calibrated and traceable to an Atomic Force Microscope results.
