Seeing Through Scattering With Computational Advances: A Review

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
In scattering media, light scrambles into random speckles and impedes our vision. Unlocking hidden information enables breakthroughs to see behind the opaqueness, inspiring applications in imaging, communication, and encryption. Unlike clear media such as clear water and air, a scattering medium is inhomogeneous, in which propagating photons are ...

Structural Eigenmodes of the Brain to Improve the Source Localization of EEG: Application to Epileptiform Activity

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Geometry and connectivity are complementary structures, which have demonstrated their ability to represent the brain's functional activity. This study evaluates geometric and connectome eigenmodes as biologically informed constraints for EEG source localization.

Aspherical Surface Measurement With Multi-Directional Lateral Shearing Phase-Shifting Interferometry

IEEE Photonics Journal
Lateral shearing interferometry is an effective method for directly measuring the depth gradient of aspherical surfaces. To address the low phase reconstruction accuracy resulting from the fact that lateral shear interferometers typically obtain only two

Wavefront‐Like LAM Method: A Case Report of Residual Potential Identification Using Local Voltage Derived From Late Annotation Mapping

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
The Wavefront‐like LAM method preserves wavefront‐based timing consistency while enabling quantitative local voltage evaluation. This method improves differentiation between low‐voltage and no‐voltage regions and suggests that residual potentials appearing isolated on conventional voltage mapping can be identified.

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Automatic Compressive Sensing of Shack–Hartmann Sensors Based on the Vision Transformer

Photonics
Shack–Hartmann wavefront sensors (SHWFSs) are crucial for detecting distortions in adaptive optics systems, but the accuracy of wavefront reconstruction is often hampered by low guide star brightness or strong atmospheric turbulence.
