Enhanced sensitivity digital holographic interferometry [PDF]

open access: yesOptics Express, 2007
Corona discharges are generally characterized by a low optical density whose detection is often near or under the limits of interferometric techniques. In this paper, we propose a method of digital holographic interferometry that enables detection with enhanced sensitivity.
