Shot Noise in Digital Holography

Published 7 Jun 2012 in physics.optics | (1206.1475v1)

Abstract: We discuss on noise in heterodyne holography in an off-axis configuration. We show that, for a weak signal, the noise is dominated by the shot noise on the reference beam. This noise corresponds to an equivalent noise on the signal beam of one photoelectron per pixel, for the whole sequence of images used to build the digital hologram.
