Metasurface‐Encoded Single‐Pixel Hyperspectral Imaging

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
A metasurface‐enabled single‐pixel hyperspectral imaging approach is proposed, achieving sub‐2‐nanometer spectral discrimination and accurate reconstruction at low sampling ratios. By uniting advanced nanophotonics with data‐driven algorithms, this framework overcomes limitations of conventional single‐pixel imaging and sets a new benchmark for compact

Prediction of beef marbling using Hyperspectral Imaging (HSI) and Partial Least Squares Regression (PLSR)

Scientia Agropecuaria, 2017
The aim of this study was to build a model to predict the beef marbling using HSI and Partial Least Squares Regression (PLSR). Totally 58 samples of longissmus dorsi muscle were scanned by a HSI system (400 - 1000 nm) in reflectance mode, using 44 samples to build t he PLSR model and 14 samples to model validation.

Non‐Invasive Detection of Foreign Matter Embedded Inside Egg Fried Rice Using Hyperspectral Transmittance Imaging

Food Frontiers, Volume 7, Issue 1, January 2026.
HSTI is a powerful tool for detecting FM within EFR. The study compares spectral ranges, light intensity, and classification models, showing that FM is most effectively identified with 110 W light intensity in the VNIR system using MLP. Pseudo‐color maps enable precise localization and contouring of FM in EFR.

Determination of the transection margin during colorectal resection with hyperspectral imaging (HSI)

International Journal of Colorectal Disease, 2019
This study evaluated the use of hyperspectral imaging for the determination of the resection margin during colorectal resections instead of clinical macroscopic assessment.The used hyperspectral camera is able to record light spectra from 500 to 1000 nm and provides information about physiologic parameters of the recorded tissue area intraoperatively ...

Laser‐Induced Breakdown Spectroscopy (LIBS) for Rapid Food Safety Monitoring: Advancements, Applications, and Future Directions

Food Safety and Health, Volume 4, Issue 1, Page 50-66, January 2026.
Laser‐induced breakdown spectroscopy (LIBS) emerges as a transformative tool for rapid, on‐site pesticide residue detection in food, offering real‐time screening with minimal sample preparation and eliminating solvent use. Although LIBS demonstrates detection limits (0.009–6.9 mg/kg) suitable for regulatory screening and aligns with green chemistry ...
