TL;DR: In this paper , an end-to-end neural network is proposed to speed up the phase map retrieval in high-throughput holographic flow cytometry, where phase maps are retrieved from digital holograms.
Abstract: The huge amount of phase maps to be numerically retrieved from digital holograms is the actual bottleneck of the high-throughput holographic flow cytometry. An end-to-end neural network is discussed to speed up the holographic processing.

TL;DR: In this paper, a pyroelectric effect activated by IR laser is used for streaming liquid nano-pico-droplets through pyro electric effect activated with IR laser for 2D and 3D manipulation of nano-drops and liquid printing.
Abstract: A new opto-nanofluidic approach named Pyro-EHD is presented for streaming liquid nano-pico-droplets through pyroelectric effect activated by IR laser. Manipulation in 2-D and 3-D of nano-drops and liquid printing with atto-Liter drops is demonstrated

TL;DR: In this paper, a repeatable and accurate method to pattern fluorescent particles into polymer microlens array and flexible elastomeric membranes is presented, which uses intense electric field generated by a Periodically Poled Lithium Niobate (PPLN) in order to direct the self-assembly electrophoretic and dielectrophoric forces.

TL;DR: In this article, nonlinear crystals are used to build coherent light sources in spectral regions where laser sources are limited, or do not exist, and optical parametric oscillators as well as harmonic and difference frequency generators are finding increasing application in high sensitivity spectroscopy.
Abstract: Nonlinear crystals are, nowadays, key devices to build coherent sources emitting radiation from the UV to the IR spectral range. Applications of nonlinear optics are primarily based on frequency conversion, through harmonic generation or sum and difference frequency mixing. These nonlinear frequency conversion techniques make possible coherent light sources in spectral regions where laser sources are limited, or do not exist. Light sources based on nonlinear crystals, like optical parametric oscillators as well as harmonic and difference frequency generators, are finding increasing application in high sensitivity spectroscopy.

TL;DR: In this article, a fast Fourier transform method of topography and interferometry is proposed to discriminate between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour generation techniques.
Abstract: A fast-Fourier-transform method of topography and interferometry is proposed. By computer processing of a noncontour type of fringe pattern, automatic discrimination is achieved between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour-generation techniques. The method has advantages over moire topography and conventional fringe-contour interferometry in both accuracy and sensitivity. Unlike fringe-scanning techniques, the method is easy to apply because it uses no moving components.
