TL;DR: In this paper, the authors proposed a holographic method with numerical reconstruction for obtaining an image of a three-dimensional object, employing a digitalised hologram of an object, and comprising a step A. wherein, starting from the digitalized hologram, extracting a phase image of said object corresponding to a bidimensional matrix MD of distance values; a step B. wherein a monodimensional subassembly SD of the distance value assembly present in matrix MD is selected, subassembling SD containing distance values dk, and a step C. wherein for each distance value dk

TL;DR: In this article, the authors used a digital holographic microscope (DHM) to carry out a noncontact and non-destructive characterization of a microheater integrated on a silicon nitride membrane and subjected to a high thermal load.

TL;DR: In this paper, several techniques (e.g., digital holography) allowed us to retrieve information on light manipulation by diatom single valves in terms of amplitude, phase and polarization, both in air and in a cytoplasmatic environment.

TL;DR: In this paper, a tunable, two-dimensional Talbot array illuminator for mid-infrared (MIR) wavelengths has been presented by deposing tin-doped indium oxide electrodes on a square-lattice-geometry poled LiNbO3 sample.

TL;DR: In this article, a new fiber optic system for structural analysis of ultra high temperature ceramic (UHTC) materials is proposed, which employs an in-fiber optical circulator and TLC 1x4 optical switch, allowing to perform a multi-sensor interrogation, to analyse many physical parameters, such as: temperature, strain, pressure, etc.
