Abstract
In this Letter, we present a method for chromatic compensation in numerical reconstruction of digitally recorded holograms based on Fresnel–Bluestein propagation. The proposed technique is applied to correct the chromatic aberration that arises in the reconstruction of RGB holograms of both millimeter- and micrometer-sized objects. The results show the feasibility of this strategy to remove the wavelength dependence of the size of the numerically propagated wavefields.
