Pupil Plane Multiplexing for Vectorial Fourier Ptychography
Laser &Photonics Reviews, EarlyView.This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

NIR/VIS Dual‐Comb Spectroscopy Comparing High and Low Repetition Rate Regimes
Laser &Photonics Reviews, EarlyView.This work compares dual‐comb spectroscopy at lower and higher repetition rates, emphasizing the inherent trade‐off between spectral and temporal resolution. The 80 MHz system provides high‐resolution spectra suitable for analyzing complex molecular structures, whereas the free‐running 1 GHz platform enables fast measurements for real‐time trace gas ...

Bathymetry from hyperspectral imagery
, 1996 This work used hyperspectral imagery to derive shallow water depth estimates. A technique to classify substrates and estimate reflectance values for the substrate types is the major contributions of this work. This was accomplished by masking different bottom types based on spectra, effects that were not included in previous methods.

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy
Nano Select, EarlyView.Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Hyperspectral signatures reveal hidden stress in soybean caused by residual nicosulfuron
New Plant Protection, EarlyView.Residual nicosulfuron in soil triggers a distinct injury–regulation–collapse trajectory in soybean. Multimodal phenotyping combining hyperspectral, UV‐MCF, and chlorophyll fluorescence imaging enables early, non‐invasive detection and dynamic monitoring of latent herbicide stress, offering a mechanistic basis for risk assessment in crop rotation ...
