Wavefront-based holographic lens optical power model for augmented reality applications
Results in PhysicsThe use of holographic optical elements (HOEs) has grown significantly in recent years, particularly in augmented reality (AR) and see-through display systems. Among them, holographic lenses (HLs) have attracted special interest due to their versatility,

3D Fourier imaging based on 2D heterodyne detection at THz frequencies
APL Photonics, 2019 Holographic imaging techniques, which exploit the coherence properties of light, enable the reconstruction of the 3D scenery being viewed. While the standard approaches for the recording of holographic images require the superposition of scattered light ...

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 ...

Holographic mensuration of suspended particles in aquatic systems [PDF]
, 1995 The distribution and dynamics of aggregates in the aquatic environment play an important role in the modelling of biogeochemical processes. Previous work on aggregates in the ocean (e.g.

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 ...

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

Aspects of Holographic Superconductivity [PDF]
, 2012 In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Achromatic 3D Multi‐Color Orbital Angular Momentum Holography
Advanced ScienceOrbital angular momentum (OAM) holography represents a transformative technique for enhancing the information channel capacity of holographic systems through the convolution of theoretical infinite OAM states with discrete sampling target images. However,
