Deconvolution Techniques in Optical Coherence Tomography: Advancements, Challenges, and Future Prospects

Laser &Photonics Reviews, Volume 19, Issue 12, June 18, 2025.
This review explores deconvolution techniques in optical coherence tomography (OCT), addressing resolution degradation from point‐spread functions (PSF). It reviews foundational principles (e.g., Richardson‐Lucy deconvolution) to advanced AI‐driven methods, emphasizing clinical translation and interdisciplinary collaboration. Real‐world implementations

Bendable Fiber Lens for Minimally Invasive Endoscopy

Laser &Photonics Reviews, Volume 19, Issue 12, June 18, 2025.
Translating ex vivo imaging to minimally invasive in vivo applications is of outstanding scientific and socioeconomic relevance. 3D imaging based on tiny lensless fiber endoscopes requires complex setups and computational schemes, so far. Bridging this gap, imaging through a unique optical fiber that mimics the functionality of a lens but is minimally ...

Full‐Space Spin‐Controlled Four‐Channel Metalens With Equal Power Distribution and Broad Bandwidth

Laser &Photonics Reviews, Volume 19, Issue 12, June 18, 2025.
In article xxxxx, Alex M. H. Wong and co‐authors propose a multifunctional full‐space metalens supporting power‐efficient, broadband operation for four spin‐controlled output channels. The metalens separates an incoming wave into four equi‐power, spin‐decoupled and function‐decoupled waves (two transmitted and two reflected).

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

The Fast Borealis Ionosphere: High Time‐Resolution Mapping of Polar Ionospheric Flows With SuperDARN

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Recent improvements to hardware for the Super Dual Auroral Radar Network systems have allowed for a much greater control of radar transmit and receive functionalities than previously possible. One of these functionalities is the application of a new operational mode, known as wide‐beam, which vastly improves the temporal resolution of the ...

Gravel Replenishment Downstream of Dams: Insights From a Flume Experiment in a Straight Embanked Channel

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Gravel replenishment (GR) is a common strategy to mitigate the negative effects of sediment deficit caused by dam regulation. However, its effectiveness in restoring dam‐regulated embanked gravel‐bed rivers with alternate bars is still unclear.
