Surface Optics at Virtual SPIE DCS 2020

SPIE Defense + Commercial Sensing, organized by the international society for optics and photonics, is underway this week in a new virtual format accessible until May 8, 2020. Registration is free and gains access to more than 600 presentations, 450 papers, and plenary speakers.

Presentations by Surface Optics customers at SPIE DCS 2020 include:

• Conference plenary speaker John Delaney, senior imaging scientist at the conservation division of the National Gallery of Art (Washington, D.C.), presenting on the topic of tri-modal imaging spectroscopy of paintings. Delaney and his colleagues are pioneering the application of hyperspectral imaging, and other advanced imaging techniques for art analysis. This presentation includes case studies on artwork by Leonardo da Vinci and Van Gogh, and images of hyperspectral data collection of Rembrandt’s Night Watch at the Rijksmuseum.
• Tania Kleynhans from the Rochester Institute of Technology’s Chester F. Carlson Center for Imaging Science presents “Automatic material classification of paintings in illuminated manuscripts from VNIR reflectance hyperspectral data cubes.” Pigment distribution maps are valuable for conservators and art historians, and applying automated algorithms could reduce the need for manual input by expert users in their creation. The National Gallery collected data for this research with a Surface Optics SOC-730 VNIR hyperspectral camera.
• Dr. Jason Zeibel from the U.S. Army Night Vision & Electronic Sensors Directorate (NVESD) presents, “Leveraging high performance hyperspectral sensors for the conservation of masterworks.” Dr. Zeibel discusses the challenge of leveraging LWIR spectral imaging for applications like art analysis, where an indoor environment is required. A new cold tunnel technique for imaging absolute emissivity is demonstrated. Validation of this technique included a comparison of results with emissivity measurements taken with the SOC-100 Hemispherical Directional Reflectometer manufactured by Surface Optics.
• Mimi Huynh, also with NVESD, presents “Laboratory and field correlation methodology” on the prediction of hyperspectral and multispectral sensor performance. Predicting sensor performance in the lab can reduce the need for field testing, saving resources. Huynh introduces the instrumentation commonly used in the NVESD lab, including the SOC-100 Hemispherical Directional Reflectometer.

Surface Optics is an SPIE organizational member and is participating in the forum’s virtual exhibition hall at booth #3022. While our team wishes we could have met with our customers and partners at the originally planned in-person event in Anaheim, we are excited to share in this unique opportunity for open access to the latest photonics research.

These and other presentations on topics related to sensors, infrared technology, laser systems, spectral imaging, radar, LIDAR, and AI/machine learning are pre-recorded. Viewers can comment on the presentations and engage with authors about their research. More than 2,300 participants have already registered for the digital forum.
