RMD developed an ultra-high-speed, high-resolution, X-ray imaging system capable of acquiring images at a rate of 120,000 frames per second (FPS) for the Department of Defense. The system was based on a fast-decay scintillator screen coupled to an ultra-fast CCD camera designed for ballistic impact studies. A specially designed X-ray source provided blur-free images of hypervelocity projectiles traveling over 18,000 miles per hour.
