Application of 3D‐Slicer combined with 3D printing technology in training neurosurgery resident physicians' imaging spatial cognition and clinical reasoning: A self‐controlled before‐ and after‐study

Anatomical Sciences Education, Volume 19, Issue 11, Page 1932-1942, November 2026.
Abstract Neurosurgical residency training requires advanced spatial cognition and 3D anatomical understanding, which traditional methods often fail to adequately develop. This study evaluated a novel educational model integrating 3D Slicer and 3D printing technology to enhance imaging spatial cognition and clinical reasoning among neurosurgery ...

Hybrid Confocal Fluorescence and Photoacoustic Microscopy for In‐Depth and Noninvasive Imaging of Biomolecule‐Functionalized 3D Scaffolds

Journal of Biophotonics, Volume 19, Issue 11, November 2026.
Illustration of 3D scaffold fabrication and functionalization with amyloid peptide fibrils, followed by nondestructive characterization using hybrid confocal fluorescence and photoacoustic microscopy. These complementary imaging modalities enable detailed visualization of scaffold architecture and selective detection of peptide fibrils, providing a ...

Phase Multiplexed Optical Computing: Reconfiguring a Multi‐Task Diffractive Optical Processor Using Illumination Phase Diversity

Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
A monochrome multi‐task diffractive optical network architecture is designed to leverage illumination‐phase multiplexing to dynamically reconfigure its output function and accurately implement a large set of complex‐valued linear transformations between an input and an output aperture.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

HoloSpec: Dispersion‐Based 4D Computational Holographic Hyperspectral Imaging

Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
HoloSpec, a compact dispersion‐based computational holographic system, achieves four‐dimensional imaging by retrieving 3D spatial structure and high‐resolution spectra from only two monochromatic snapshots. Using a single prism and a monochrome sensor, it resolves 430 spectral channels with 3 nm experimental resolution and 30 μm$\mathrm{\mu}\mathrm{m}$

Ultra-Sensitive Wavefront Measurement Using a Hartmann Sensor [PDF]

Optics Express, 2007
We describe a Hartmann sensor with a sensitivity of λ /15,500 at λ= 820nm. We also demonstrate its application to the measurement of an ultra small change in wavefront and show that the result agrees with that expected to within λ/3,300.Aidan F.
