SNR and Noise Variance Estimation in Polarimetric SAR Data [PDF]
, 2013 The problem of estimating the signal-to-noise ratio (SNR) of the cross-polarised channels and the noise variance in polarimetric synthetic aperture radar (SAR) data is dealt with.

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Invariance Properties and Measurement of Correlation Between Two Propagating or Evanescent Waves
Laser &Photonics Reviews, EarlyView.This work analyses the strength of correlation between two propagating or evanescent plane waves generally expressed in different frames. Interferometric and nanoscattering‐based methods, respectively, are demonstrated for their measurement. The results show that the applied measure of correlation remains invariant under unitary polarization ...

Laser &Photonics Reviews, EarlyView.A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

Comparison of Methods for Classification of Land Cover using Poarimetric SAR data [PDF]
, 2006 Polarimetric SAR data are coherent by nature of the principle of operation. However, most often incoherent ap-proaches are chosen for the post-processing in order to apply conventional averaging and statistical methods.

Automatic insect identification, counting, and monitoring techniques: a review
Pest Management Science, EarlyView.Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

Remote Sensing in Ecology and Conservation, EarlyView.Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...
