Linear Variable Filter‐Based Wide‐Field Hyperspectral Camera for Multiplex Immunoplasmonics Imaging

Journal of Biophotonics, Volume 19, Issue 8, August 2026.
A compact LVTF‐based wide‐field hyperspectral camera integrated with reflected light microscopy enables rapid, high‐resolution imaging of plasmonic nanoparticles on cells. The system improves spatial resolution, signal‐to‐noise ratio, and acquisition speed over push‐broom methods, achieving accurate multiplex nanoparticle classification (97% F‐score ...

Differentiating solar lentigines from post‐inflammatory hyperpigmentation with hyperspectral imaging: A pilot study

International Journal of Cosmetic Science, Volume 48, Issue 4, Page 738-746, August 2026.
This preliminary study attempted to characterize solar lentigines and post‐inflammatory hyperpigmentation (PIH) observed on Japanese women. Colorimetric features and chromophore concentrations were measured using hyperspectral imaging for each hyperpigmentation type.

Tunable Extraordinary Optical Transmission in the Long‐Wavelength Infrared Range Using Electrostatic MEMS Actuation

Advanced Materials Technologies, Volume 11, Issue 14, 22 July 2026.
A MEMS‐integrated metamaterial filter enables continuous, low‐voltage spectral tuning in the long‐wavelength infrared (LWIR). The device employs extraordinary optical transmission in a dual suspended metasurface stack, where electrostatic actuation precisely controls the intermembrane air gap.

Refractive Index–Correlated Pseudocoloring for Adaptive Color Fusion in Holotomographic Cytology

Cytometry Part A, Volume 109, Issue 7, Page 500-512, July 2026.
ABSTRACT Conventional bright‐field (BF) cytology of thyroid fine‐needle aspiration biopsy (FNAB) suffers from staining variability and limited subcellular contrast. Here, we present a refractive index–correlated pseudocoloring (RICP) framework that integrates quantitative refractive index (RI) maps obtained by holotomography (HT) with color BF images ...

HSI-IPGAN: Hyperspectral Image Inpainting via Generative Adversarial Network

, 2023
Abstract Due to the instability of the hyperspectral imaging system and the atmospheric interference, hyperspectral images (HSIs) often suffer from losing the image information of areas with different shapes, which significantly degrades the data quality and further limits the effectiveness of methods for subsequent tasks.
