Methods for the Epipolarity Analysis of Pushbroom Satellite Images Based on the Rational Function Model

IEEE Access, 2020
Epipolarity is the foundation of epipolar resampling, which is used to eliminate the vertical disparity between stereo pairs in stereo matching. To analyze the epipolarity of pushbroom satellite images, this paper compares three methods based on the ...

Non‐Destructive Analysis of Phenolic and Flavonoid Contents in Medicinal Plant Powders Using Hyperspectral Imaging and Variable Selection

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Phenolic and flavonoid contents in medicinal plants are essential to their growth and development and provide numerous health benefits, yet their quantification using traditional wet chemistry is labor‐intensive and time‐consuming. This study utilized the combination of two benchtop hyperspectral imaging (HSI) systems, namely short‐wave ...

High-throughput, multiplexed pushbroom hyperspectral microscopy

Optics Express, 2008
We describe a high-throughput hyperspectral microscope. The system replaces the slit of conventional pushbroom spectral imagers with a static coded aperture mask. We present the theoretical underpinnings of the aperture coded spectral engine and describe two proof-of-concept experimental implementations. Compared to a conventional pushbroom system, the

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 ...
