Single-shot multispectral imaging through a thin scatterer

Optica, 2019
Performing imaging with scattered light is challenging due to the complex and random modulation imposed upon the light by the scatterer. Persistent correlations, such as the optical memory effect (ME), enable high-fidelity, diffraction-limited imaging ...

Broadband All‐Optical Memtransistor Based on Organic Cocrystals for Noise‐Robust Motion Recognition

Advanced Science, EarlyView.
This work presents an all‐optical synaptic transistor using DTT‐TCNQ organic charge transfer cocrystals, achieving broadband bidirectional modulation (395–808 nm) with highly linear synaptic plasticity (nonlinearity coefficients αp = 0.00191, αd = 0.00305).

Evaluation of gastric tube blood flow by multispectral camera and fluorescence angiography

Surgery Open Science
Background: Evidence regarding the application of the multispectral camera for blood flow measurement is insufficient, and its performance has not been compared with the conventional indocyanine green (ICG) method.

A convex formulation for hyperspectral image superresolution via subspace-based regularization

, 2014
Hyperspectral remote sensing images (HSIs) usually have high spectral resolution and low spatial resolution. Conversely, multispectral images (MSIs) usually have low spectral and high spatial resolutions. The problem of inferring images which combine the

Computational multispectral video imaging [Invited]

Journal of the Optical Society of America A, 2017
Multispectral imagers reveal information unperceivable to humans and conventional cameras. Here, we demonstrate a compact single-shot multispectral video-imaging camera by placing a micro-structured diffractive filter in close proximity to the image sensor.

PRDM1+ Malignant Cells Mediate an Immunosuppressive Landscape and Resistance to Neoadjuvant Chemoradiotherapy and Immunotherapy in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
Integrated scRNA‐seq, scTCR‐seq analysis, and functional assays identify PRDM1+ malignant epithelial cells with hyper lipid peroxidation characteristics that demonstrate reduced responsiveness to the nICRT treatment. Principal factor PRDM1 activates cysteine metabolism genes to modulate lipid peroxidation (an intrinsic cellular pathway related to ...

Multisensor Analysis of Spectral Dimensionality and Soil Diversity in the Great Central Valley of California

Sensors, 2018
Planned hyperspectral satellite missions and the decreased revisit time of multispectral imaging offer the potential for data fusion to leverage both the spectral resolution of hyperspectral sensors and the temporal resolution of multispectral ...

Label‐Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes

Advanced Science, EarlyView.
Mid‐infrared photothermal microscopy enables label‐free structural, molecular, and functional imaging of protein aggregates in astrocyte cells. The processes of astrocytes differentiated on a nanomaterial interface are characterized by α‐helical signatures combined with enhanced interfacial thermal resistance properties, while the cell soma of non ...

Multispectral Stokes Imaging Polarimetry Based on Color CCD

IEEE Photonics Journal, 2016
In this paper, we propose a method for multispectral imaging polarimetry based on a color charge-coupled device (CCD), which can simultaneously measure the Stokes vectors at three wavelengths without significantly increasing the complexity of the system ...
