TL;DR: In this article, the most significant achievements reached in 2013 on holographic imaging are described and discussed in detail, and the authors describe shortly what appeared to them to be the most important achievements reached.

TL;DR: A compact twin-beam interferometer that can be adopted as a flexible diagnostic tool in microfluidic platforms with twofold functionality with novel configuration that allows 3D tracking of micro-particles and can simultaneously furnish Quantitative Phase-contrast maps of tracked micro-objects by interference microscopy, without changing the configuration.

TL;DR: In this paper, the amplitude and phase reconstruction of images from digital holograms by the Fresnel transformation method is limited by the pixel width in the reconstructed image plane, which depends on distance, wavelength, and number of pixels in the hologram.

TL;DR: In this article, the pyroelectric effect was used to obtain wettability patterning by an electrodeless configuration of the niobate crystal lattice, where surface charges inducing the effect were generated pyroelectrically and spatially modulated by the domain grating.

TL;DR: In-situ monitoring of domain reversal in congruent lithium niobate by a digital holographic technique is described, using holography to reconstruct both amplitude and phase of the wavefield transmitted by the sample to reveal the phase shift induced by adjacent reversed domains during the poling.
