Detection and Identification of Plastics using SWIR Hyperspectral Imaging

Most plastics are typically transparent in the visible spectral range, rendering them challenging to detect using silicon-based vision sensors. In this work a SWIR hyperspectral imaging system is used to collect the SWIR hyperspectral signatures as well as spatial information of a variety of plastics outdoors to test this technology for plastic debris detection and […]

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

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

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 […]
