A John White Alexander painting A comparison of imaging technologies for resolving a painting under another painting

March 7, 2019

Reflectance imaging spectroscopy (RIS) in the visible and near infrared is revolutionizing the way cultural heritage investigators may analyze paintings nondestructively. In an ongoing, highly collaborative project, the authors are investigating a painting by American artist John White Alexander (1856–1915). The painting, titled A Study in Pink, is in the collection of the Virginia Museum […]

Advanced Imaging System with Multiple Optical Sensing Modes

May 8, 2018

The Spectral-Polarimetric Hypersensor (SPH) is a new compact, solid state, video rate imaging system with no moving parts capable of capturing up to 16 bands of both spectral and polarimetric content simultaneously. For these imagers, which are an adaptation of a plenoptic system, all elements for a given super pixel sample the same point in […]

Spectral Imaging Powered Industrial Flare Monitoring Camera

November 3, 2016

Real-time spectral imaging flare monitoring means real environmental impact Industrial flares are widely used as safety devices in petroleum refineries, chemical plants and oil and gas fields. Waste process gases are vented to flares to be safely combusted over the flare tips, avoiding industrial accidents and reducing air pollution. But recent studies have found flares […]

Detecting red blotch disease in grape leaves using hyperspectral imaging

May 23, 2016

Red blotch disease is a viral disease that affects grapevines. Symptoms appear as irregular blotches on grape leaves with pink and red veins on the underside of the leaves. Red blotch disease causes a reduction in the accumulation of sugar in grapevines affecting the quality of grapes and resulting in delayed harvest. Detecting and monitoring […]

Hyperspectral imaging for differentiation of foreign materials from pinto beans

September 1, 2015

Food safety and quality in packaged products are paramount in the food processing industry. To ensure that packaged products are free of foreign materials, such as debris and pests, unwanted materials mixed with the targeted products must be detected before packaging. A portable hyperspectral imaging system in the visible-to-NIR range has been used to acquire […]

Multimodal Hyperspectral Optical Microscopy

November 24, 2014

We describe a unique approach to hyperspectral optical microscopy, herein achieved by coupling a hyperspectral imager to various optical microscopes. Hyperspectral fluorescence micrographs of isolated fluorescent beads are first employed to ensure spectral calibration of our detector and to gauge the attainable spatial resolution of our measurements. Different science applications of our instrument are then […]
