Computer Generated Holograms of 3D Points Cloud [PDF]

, 2018
Computer generated holography is a method of using numerical methods to simulate the physical processes underlying a real hologram’s optical recording and reconstruction i.e. the method of digitally generating holographic interference patterns.

Holo-U²Net for High-Fidelity 3D Hologram Generation

Sensors
Traditional methods of hologram generation, such as point-, polygon-, and layer-based physical simulation approaches, suffer from substantial computational overhead and generate low-fidelity holograms.

Energy‐Resolved Localized Surface Plasmon Resonances With Non‐Monochromated STEM‐EELS Assisted by Multivariate Analysis

Small Methods, EarlyView.
Transmission Electron Microscopy is a powerful technique, able to provide morphological, chemical, and optical/electronic information, yet some of these features require the use of highly expensive machines such as monochromated microscopes. In this work, we used low dose, low voltage, and mathematical treatment to gain energy resolution in an ...

Three-dimensional computer holography with phase space tailoring

PhotoniX
Computer holography is a prominent technique for reconstructing customized three-dimensional (3D) diffraction fields. However, the quality of optical reconstruction remains a fundamental challenge in 3D computer holography, especially for the 3D ...

Hyperspectral and Multispectral Image Fusion via Deep Generalised Linear Mixed Model

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Hyperspectral–multispectral image fusion is an incomplete information fusion problem, and directly embedding information can lead to modality‐specific responses and cause spectral distortion, whereas the strong interband redundancy of hyperspectral images makes full‐dimensional fusion inefficient.

Correlative X‐ray imaging and fluorescence microscopy in hydrated environments

Journal of Synchrotron Radiation, EarlyView.
We present a combined imaging platform that integrates beamline‐compatible fluorescence microscopy with scanning small‐angle X‐ray scattering to enable sequential multimodal investigations of hydrated cells under near‐native conditions. We apply our method to ordered cytoskeletal structures in different cell types and demonstrate the direct correlation

Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.
