After taking on a virtual format in 2020 and 2021, SPIE’s Defense + Commercial Sensing (DCS) will return to the exhibition hall April 3-7. The event will take place at the Gaylord Palms Resort and Convention Center outside Orlando, Fla. Gaylord Palms Resort and Convention Center. The event features four conference tracks and hundreds of technical presentations, as well as an exhibition hall showcasing the latest innovations in sensing, hands-on demonstrations, plenary sessions, and 19 courses focused on training and education. The event features 39 specially focused conferences across technologies including infrared imaging, autonomous sensing, multispectral and hyperspectral, artificial intelligence, polarization, and more. Exhibitors from over 250 companies (as of press time) will display their technologies and products in a vibrant exhibition hall. The exhibition kicks off Tuesday, April 5. In the Materials and Devices track, conferences and sessions will explore infrared materials, image sensors, photon counting, energy harvesting, and quantum technologies. Five conferences make up the track. Applications for these technologies include wearables, cybersecurity, information processing, energy storage, and drones. On Wednesday, April 6, Jacob Taylor of the University of Maryland and chief science officer at Riverlane will deliver the plenary address for the track in a talk titled “The Birth of Quantum Engineering.” The Imaging and Analytics track features nine conferences, which will include those in spectral imaging, computational image processing, metrology, and 3D imaging. Presentations will include applications in security and defense, climate monitoring, big data, deep learning, machine vision, target detection, and tracking. Karl Berggren, professor of electrical engineering at MIT, will deliver the track’s plenary address April 6, following Taylor’s presentation. Berggren will deliver “Superconducting Nanowire Single-Photon Detectors.” Research on fiber optic sensors, radar, laser radar, infrared technologies, thermal imaging, and more will be featured in the 10 conferences included as part of the Advanced Sensing and Imaging track. Applications span security, structural sensing and health monitoring, nondestructive inspection, tracking, and ranging. The plenary for the Advanced Sensing and Imaging track will be presented by Edmund Zelnio of the Autonomy Technology Research Center in the Air Force Research Laboratory. Zelnio will talk about “Automatic Target Recognition: Past, Present, Future.” The final and largest track, featuring 13 conferences, is Next Generation Sensor Systems and Applications. The track includes papers that highlight cutting-edge research focused on emerging technologies for specific applications such as autonomous systems; chemical, biological, radiological, and nuclear defense; agriculture and food safety; and cyber-physical systems/IoT. Awards honoring outstanding achievement of the research community, networking and community events, and panel discussions round out the program. A multiday job fair benefitting job seekers and employers, as well as a running list of company announcements posted online, will complement the program. Vaccination regulations are in effect for SPIE DCS; a full list of regulations and expectations is available at the event website via www.spie.org.
