Diffraqtion develops "quantum camera” for space-based imaging. It reverses the process of deriving an image from photonic data (using AI model) and opens the possibility of collecting images using sensors that don’t require telescope and other heavy components. That just might be the key to shooting down highly maneuverable hypersonic missiles, as envisioned by the White House’s Golden Dome effort. The method proposed by Diffraqtion might lower the cost of the imaging systems on space-based interceptors, or even reduce the number needed to do the job.
