Abstract
We comment on a recent Letter by Hincapie et al.
[Opt. Lett. 40, 1623 (2015)], in which the authors proposed a method to reduce the speckle noise in digital holograms. This method was previously published by us in Maycock [“Improving reconstructions of digital holograms,” Ph.D. thesis (National University of Ireland, 2012)] and
Maycock and Hennelly [Improving Reconstructions of Digital Holograms: Speckle Reduction and Occlusions in Digital Holography (Lambert Academic, 2014)]. We also wish to highlight an important limitation of the method resulting from the superposition of different perspectives of the object/scene, which was not addressed in their Letter.
