We look forward to gathering 15 - 17 April 2025 at the Gaylord Palms Resort & Convention Center in Orlando, Florida, US, for SPIE Defense + Commercial Sensing, the most important event for learning about sensing technologies being rapidly acquired and deployed within public, security, and government applications. The 2025 program—40 conferences and 20 courses—is now online. Come hear the latest advancements in sensors, infrared, laser systems, spectral imaging, radar, lidar, autonomous systems, and other findings with the community.
