Mapping the pigment distribution of Vermeer’s Girl with a Pearl Earring

open access: yesHeritage Science, 2020
As part of the 2018 Girl in the Spotlight project, reflectance and molecular fluorescence imaging spectroscopy (RIS, FIS), and macroscale X-ray fluorescence scanning (MA-XRF) were performed on Johannes Vermeer’s Girl with a Pearl Earring (c.

Automated classification of brain tissue: comparison between hyperspectral imaging and diffuse reflectance spectroscopy [PDF]

open access: yesMedical Imaging 2020: Image-Guided Procedures, Robotic Interventions, and Modeling, 2020
In neurosurgery, technical solutions for visualizing the border between healthy brain and tumor tissue is of great value, since they enable the surgeon to achieve gross total resection while minimizing the risk of damage to eloquent areas. By using real-time non-ionizing imaging techniques, such as hyperspectral imaging (HSI), the spectral signature of

Supercontinuum ultra wide range confocal microscope for reflectance spectroscopy of living matter and material science surfaces

open access: yesAIP Advances, 2011
We report the design and implementation of a new reflectance laser scanning confocal system with spectroscopy imaging capabilities. Confocal spectroscopy is achieved by using a very broad spectral range supercontinuum source capable of high precision ...

Measuring and imaging of transcutaneous bilirubin, hemoglobin, and melanin based on diffuse reflectance spectroscopy

open access: yesJournal of Biomedical Optics, 2023
Evaluation of biological chromophore levels is useful for detection of various skin diseases, including cancer, monitoring of health status and tissue metabolism, and assessment of clinical and physiological vascular functions. Clinically, it is useful to assess multiple different chromophores in vivo with a single technique or instrument.To ...

Intraspecific genetic variation of a Fagus sylvatica population in a temperate forest derived from airborne imaging spectroscopy time series

open access: yesEcology and Evolution, 2020
The growing pace of environmental change has increased the need for large‐scale monitoring of biodiversity. Declining intraspecific genetic variation is likely a critical factor in biodiversity loss, but is especially difficult to monitor: assessments of

Terahertz Spectroscopy and Brewster Angle Reflection Imaging of Acoustic Tiles [PDF]

open access: yesJournal of Spectroscopy, 2017
A Brewster angle reflection imaging apparatus is demonstrated which is capable of detecting hidden water-filled voids in a rubber tile sample. This imaging application simulates a real-world hull inspection problem for Royal Canadian Navy Victoria-class submarines.

Artificial Intelligence for Pigment Classification Task in the Short-Wave Infrared Range

open access: yesSensors, 2021
Hyperspectral reflectance imaging in the short-wave infrared range (SWIR, “extended NIR”, ca. 1000 to 2500 nm) has proven to provide enhanced characterization of paint materials.
