Higher Speed Multispectral Imaging Using a Thin Liquid Crystal Layer in Metal Cavity and Artificial Intelligence Reconstruction Algorithm

open access: yesLaser &Photonics Reviews, EarlyView.
A rapid multispectral imaging system is presented that integrates a 4 µm‐thick liquid crystal spectral modulator in a metal–insulator–metal (MIM) configuration with a multi‐bandpass filter (MBF). Coupled with a custom AI‐based reconstruction algorithm, the system enables accurate food quality monitoring and demonstrates the potential to capture a ...

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Evaluation of food safety in the handling of home enteral nutrition based on a new contamination risk classification: A cross‐sectional study

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Home enteral nutrition (HEN) offers clinical benefits and is increasingly used, although handling‐related health risks remain unclear. This study assessed food safety in HEN using a new contamination risk classification. Methods First, the inter‐rater reliability of the Food Safety for Handling HEN checklist was analyzed in 25 ...
