The Department of Defense, through DARPA, is seeking innovative solutions under the SBIR program for a project titled "Narcissus," which aims to develop computational imaging methods utilizing the window surfaces of commercial high-rise buildings as light-collecting mirrors. The primary objective is to create a system capable of detecting faint objects in space or the upper atmosphere by leveraging the reflective properties of large areas of window glass, specifically targeting a 10-story building with 900 window panes. This initiative builds on previous research validating the feasibility of using existing building infrastructure for advanced imaging applications, with a focus on low-cost and scalable solutions. Interested parties should prepare to submit proposals by the application due date of October 22, 2025, with the opportunity details available at the provided source link.
