Generating Multi‐Depth 3D Holograms Using a Fully Convolutional Neural Network

Advanced Science
Efficiently generating 3D holograms is one of the most challenging research topics in the field of holography. This work introduces a method for generating multi‐depth phase‐only holograms using a fully convolutional neural network (FCN).

A human erythrocytes hologram dataset for learning-based model training

Data in Brief
This manuscript presents a paired dataset with experimental holograms and their corresponding reconstructed phase maps of human red blood cells (RBCs). The holographic images were recorded using an off-axis telecentric Digital Holographic Microscope (DHM)

Reviewing the Inclusion of Artists’ Holograms in the Permanent Collections of Fine Art Museums

Arts, 2019
Opening in 1976 with the exhibition, “Through the Looking Glass”, the Museum of Holography (MOH) emphasized from the beginning the importance of artistic holography with the inclusion of several holograms by artists whose primary practice was

A data extraction system for underwater particle holography

, 2000
Pulsed laser holography is an extremely powerful technique for the study of particle fields as it allows instantaneous, noninvasive high-resolution recording of substantial volumes.

Multiplexing holograms in LiNbO3FeMn crystals [PDF]

, 1999
Persistent holograms are recorded with red light in lithium niobate crystals doped with manganese and iron. Different erasure mechanisms are investigated, and a recording schedule for multiplexing holograms with equal diffraction efficiencies is proposed.

Refractive Index–Correlated Pseudocoloring for Adaptive Color Fusion in Holotomographic Cytology

Cytometry Part A, EarlyView.
ABSTRACT Conventional bright‐field (BF) cytology of thyroid fine‐needle aspiration biopsy (FNAB) suffers from staining variability and limited subcellular contrast. Here, we present a refractive index–correlated pseudocoloring (RICP) framework that integrates quantitative refractive index (RI) maps obtained by holotomography (HT) with color BF images ...

Assessment of pulmonary vascular anatomy: comparing augmented reality by holograms versus standard CT images/reconstructions using surgical findings as reference standard

European Radiology Experimental
Background We compared computed tomography (CT) images and holograms (HG) to assess the number of arteries of the lung lobes undergoing lobectomy and assessed easiness in interpretation by radiologists and thoracic surgeons with both techniques.

UHU® adhesive holograms replication

, 2008
It is possible to apply a new recording material with high diffraction efficiency (of the order of 82.3%) to replicate computer phase or analogical holograms. This material is the all purpose adhesive UHU®.

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.
