Custom-Technology Single-Photon Avalanche Diode Linear Detector Array for Underwater Depth Imaging

Sensors, 2021
We present an optical depth imaging system suitable for highly scattering underwater environments. The system used the time-correlated single-photon counting (TCSPC) technique and the time-of-flight approach to obtain depth profiles.

Fundamental limits to depth imaging with single-photon detector array sensors

Scientific Reports, 2023
Single-Photon Avalanche Detector (SPAD) arrays are a rapidly emerging technology. These multi-pixel sensors have single-photon sensitivities and pico-second temporal resolutions thus they can rapidly generate depth images with millimeter precision.

Integration of Refractive Microlenses on BP/MoS2 Photodiodes for Enhanced Infrared Photodetection

Small, EarlyView.
This study demonstrates the successful integration of black phosphorus/molybdenum disulfide infrared photodetectors with refractive microlenses to significantly enhance detection. The design achieves a 20‐fold photocurrent enhancement, enabling a room‐temperature detectivity of 1.83 × 109 cmHz1/2W−1, and demonstrates high‐resolution (1023 × 768) single‐

SMART: Speedy Measurement of Arabidopsis Rosette Traits

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Most computer vision‐ and machine learning‐based plant phenotyping systems compute traits such as shape and size rather than the color distribution of the plant surface, even though color can provide important insights into plant physiology. Therefore, we developed Speedy Measurement of Arabidopsis Rosette Traits (SMART), an open‐source plant ...

Development and deployment of a public mid‐density genotyping panel for crimson clover (Trifolium incarnatum L.) based on whole‐genome re‐sequencing of diverse germplasm

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Crimson clover (Trifolium incarnatum L.) is an obligately outcrossing, cool‐season annual legume valued for forage and cover cropping, yet genomic resources to support systematic improvement are limited. We performed the first whole‐genome re‐sequencing of global crimson clover germplasm to (i) develop a public mid‐density enrichment capture ...
