Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

open access: yesJournal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.

Size‐ and Depth‐Extended Aerial 3D Display Using Fresnel‐Lens‐Enhanced AIRR

open access: yesJournal of the Society for Information Display, EarlyView.
A size‐ and depth‐extended three‐dimensional (3D) aerial display is realized by combining a light‐field display with a magnifying lens and a Fresnel‐lens‐enhanced aerial imaging by retro‐reflection (LeAIRR) system. The magnifying lens enlarges the virtual light‐field display plane without increasing the physical panel size, extending the aerial image ...

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation

open access: yesETRI Journal, 2019
Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.

Wide‐Field Autostereoscopic 3D Display Enabled by Isolated Microlens Array and Gradual Radius Lens Design

open access: yesJournal of the Society for Information Display, EarlyView.
This paper proposes an Isolated Microlens Array (I‐MLA) with Gradual Radius Lens (GRL) design for a wide‐field autostereoscopic floating 3D display in compact form. Extended coding pitch and directional mesh eliminate crosstalk, while radially varying microlens curvature maintains sharp images at large angles. Simulations show a practical continuous 40°

Augmented Reality Integration Improves Ergonomics in Dynamic Navigation for Dental Implant Surgery

open access: yesJournal of the Society for Information Display, EarlyView.
This model‐based study demonstrates that integrating augmented reality (AR) to project X‐Guide navigation data directly onto the surgical field eliminates attention shifts between the patient and monitor, enhancing ergonomic efficiency. The AR system, which projects digital guidance directly into the surgeon’s line of sight, achieved high precision and

Light-Front Holographic Quantum Chromodynamics

open access: yes, 2013
Anti-de Sitter space in five dimensions provides an exact geometrical representation of the conformal group. Remarkably, gravity in AdS$_5$ space is holographically dual to frame-independent light-front Hamiltonian theory, derived from the quantization ...

Thin Maxwellian Virtual Reality Near‐Eye Display Using Holographic Optical Element and Mini‐Fresnel Lens Array

open access: yesJournal of the Society for Information Display, EarlyView.
A thin Maxwellian‐view VR near‐eye display based on a holographic optical element (HOE) is presented. Integrating the HOE with the display panel eliminates the structural gap, achieving an 8‐mm internal spacing. Accommodation‐independent image sharpness is experimentally verified over a 0‐ to 3.3‐D range, mitigating the vergence–accommodation conflict.
