Special Issue on Metaverse: Optics & Photonics
截稿日期: 2023-10-31

Metaverse, a portmanteau of “meta” and “universe”, is now becoming a phenomenon amongst both the industry and academia. But when people get asked what is metaverse, they are likely to think of computer technologies, e.g., virtual reality (graphics) and blockchain. This special issue aims to pivot the core of metaverse to the optics or photonics as what you see is what you get, and to curate a collection of the latest impactful research in this field. In particular, we look forward to the interdisciplinary crossover for disruptive or game-changing discoveries. Topics to be featured in this issue include (but are not limited to):

Wearable devices
Magnifiers
Free-space combiners
Waveguides
Retinal projection/scanning
Contact/intraocular lenses
3D imaging and sensing
Computational imaging
Holography
LIDAR
Bio-inspired devices
Biophotonics
Retinal implants/bionic eyes
Vision sciences
Visual optics
Computational human vision

Special Issue on Developments in Photoelasticity and Diverse Applications
截稿日期: 2024-01-31

The recent years in science and engineering has seen a resurgence in the use of photoelasticity in diverse fields ranging from agricultural applications to locomotion of organisms to mitigating stresses or identifying defects in 3D electronics. Novel applications in biomedical and even conventional stress analysis involving complex loading and boundary conditions in aerospace, civil, mechanical, and manufacturing engineering fields have also been the focus. Three-dimensional models with porosity and varied aggregates of arbitrary shapes that were not possible hitherto have now become possible with the use of rapid prototyping technologies, which is promising to develop more realistic models for studying material behaviour. Comparisons with numerical models to validate as well as to improve numerical frameworks in terms of boundary conditions using innovative methods of comparisons based on plotting the isochromatic/isoclinic fringe fields rather than stress separation has made stress analysis even more attractive.

Sleek and compact equipment along with processing software for photoelastic analysis based on the digital photoelastic techniques developed over the last three decades are available for researchers from various fields to use. The availability of polarizing cameras and deep learning methodologies for data processing has renewed and instilled new interest in the minds of young scientists to further contribute to the development of photoelastic methodologies and make them tangible for application to novel domains.This special issue is to highlight these developments and original contributions/review articles are invited on all aspects of photoelasticity/photoplasticity and its diverse applications. Further, it aims to provide a platform to examine unaddressed aspects, develop new approaches, and suggest new perspectives.
Below is a non-restrictive list of topics:

Granular applications of photoelasticity ranging from understanding dynamic phenomena to improving agricultural production• Biomedical and biomimetics applications involving soft tissues, dentistry, development of tendons, ocular applications• Three-dimensional analysis of porous media, heterogeneous media and comparisons with numerical modelling and attempts to develop simplified analytical models• Stress analysis applications involving complex boundary conditions, interaction of stress-raisers, residual and assembly stresses• Photoelasticity beyond the visual range• Development of newer digital photoelastic techniques, advancements in polarization cameras, deep learning methods• Photoelasticity/photoplasticity in manufacturing and process monitoring applications• Glass stress analysis• Use of photoelasticity in engineering, medical as well as biological education
