Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

Laser &Photonics Reviews, Volume 19, Issue 21, November 6, 2025.
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 ...

Prediction of nutritive values, morphology and agronomic characteristics in forage maize using two applications of NIRS spectrometry

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
This study evaluates nutritive, morphological and agronomic characteristics of forage maize predicted by using a high-quality near-infrared (NIR) spectrometer and an NIR hyperspectral-imaging technique using partial least squares (PLS) regression models.

Hyperspectral Push-Broom Microscope Development and Characterization

IEEE Access, 2019
Currently, the use of hyperspectral imaging (HSI) for the inspection of microscopic samples is an emerging trend in different fields. The use of push-broom hyperspectral (HS) cameras against other HSI technologies is motivated by their high spectral ...

Detection of Saturation in High-Resolution Pushbroom Satellite Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
Over the last decade, DigitalGlobe has launched a series of commercial Earth imaging satellites. These high-resolution satellite imageries provide an increasingly abundant data source for remote mapping of the Earth surface and its temporal variability. Among the factors affecting image quality is saturation of the charge-coupled device due to improper

High‐speed autonomous obstacle avoidance with pushbroom stereo

Journal of Field Robotics, 2017
AbstractWe present the design and implementation of a small autonomous unmanned aerial vehicle capable of high‐speed flight through complex natural environments. Using only onboard GPS‐denied sensing and computation, we perform obstacle detection, planning, and feedback control in real time.

Why the pushbroom scan, and its limit.

Journal of the Japan society of photogrammetry and remote sensing, 1992
Pushbroom scan will be used widely in future high resolution imaging spectrometer. What is the reason? Why will not be used the mechanical scan for high resolution? In this paper, comparison of signal integration time was done and it was shown that the pushbroom scan is the ultimate scan scheme from the viewpoint of integration time.

Onboard Real-Time Hyperspectral Subpixel Mapping With Pushbroom Neural Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Satellite hyperspectral images provide fine spectral information but often suffer from coarse spatial resolution. This may result in mixed pixels containing multiple land cover classes, degrading the performance of conventional classification methods ...
