Influence of shot noise on phase measurement accuracy in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Benjamin Rappaz, Pierre Marquet, Jonas Kühn, Florian Charrière

Digital Holographic Microscopy (DHM) is a single shot interferometric technique, which provides quantitative phase images with subwavelength axial accuracy. A short hologram acquisition time (down to microseconds), allows DHM to offer a reduced sensitivity ...

A Cooperative Backup System

Sameh Mohamed Elnikety

We present a novel peer-to-peer backup technique that allows computers connected to the Internet to back up their data cooperatively: Each computer has a set of partner computers, which collectively hold its backup data. In return, it holds a part of each ...
