Operating in perpetual motion? Coping with the dark side of global boundary spanning

Global Strategy Journal, EarlyView.
Abstract Research Summary This paper explores how individuals experience and cope with the demands of global boundary spanning in multinational enterprises (MNEs). We foreground temporary colocation as a modality through which mobile global boundary spanners repeatedly traverse multiple boundaries, triggering intense demands with adverse consequences ...

Conversion of 2D picture to color 3D holography using end-to-end convolutional neural network

PhotoniX
In the field of holographic 3D display, generating a three-dimensional (3D) computer-generated hologram (CGH) from a single two-dimensional (2D) image has been a significant challenge due to the high-dimensionality of the problem.

Contact printing of on-axis computer-generated hologram on silver halide emulsion

, 1991
The authors have shown that the phase profile of a binary image recorded on the silver halide emulsion is flat in each hologram cell despite an uneven surface-relief profile. It is therefore possible to copy high quality computer-generated holograms (CGH'

Complex modulation computer-generated hologram with occlusion effect by a fast hybrid point-source/wave-field approach

, 2015
International audienceWe propose a fast Computer-Generated Hologram (CGH) computation method with occlusion effect based on a hybrid point-source/wave-field approach. Whereas previously proposed methods tried to reduce the computational complexity of the

Clinical Applications of 3D Specimen Scanning and Margin Mapping in Musculoskeletal Oncology: A 36 Patient Case Series

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background Text‐based pathology reports inadequately communicate complex three‐dimensional (3D) relationships in musculoskeletal oncology, potentially contributing to errors in re‐resection and adjuvant treatment planning. While our prior 7‐case pilot study established technical feasibility, the scalability of this workflow and its utility as ...

Computer-generated holograms of three-dimensional realistic objects recorded without wave interference

, 2001
We propose a method of synthesizing computer-generated holograms of real-life three-dimensional (3-D) objects. An ordinary digital camera illuminated by incoherent white light records several projections of the 3-D object from different points of view ...

Coherent Optical Pattern Recognition Using Computer-Generated Holograms

, 1991
Coherent optical pattern recognition using computer-generated holograms A relatively inexpensive optical processing system is described which uses a TV camera to demonstrate visually many of the features of Fourier transform theory with particular ...

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Nonlocal Leaky Mode Metasurfaces for Mode‐, Angle‐, and Polarization‐Multiplexed Holography With Thermal Light

Laser &Photonics Reviews, EarlyView.
Nonlocal leaky mode metasurfaces reconstruct multiplexed holograms directly from unfiltered thermal light. High‐Q leaky guided modes compress broadband halogen emission into narrowband channels, enhancing temporal coherence a hundredfold, while a single nanohole array encodes independent images addressed by mode, angle, and polarization, establishing ...

Single‐Lens Counter‐Focused Ultrashort Laser Pulses for Enhanced Microplasma Formation Inside Silicon

Laser &Photonics Reviews, EarlyView.
A polarization‐dependent liquid–crystal spatial light modulator is used to generate coaxial double‐focus laser beams with independently tunable focal separation and intensity. Applied to silicon, this configuration enables counterpropagating pulse interactions using a single focusing element, enhancing nonlinear excitation and achieving near‐critical ...
