High Speed X-ray Imagers

Ultrafast X-Ray Imagers

RMD has pioneered ultrafast X-ray imaging technology and over the past 15 years has designed and delivered high-resolution systems for applications ranging from time-resolved studies at synchrotron sources to ballistic impact analysis and NDE of machinery during operation.

Our systems provide multiple images over a wide range of X-ray energies and at speeds ranging from tens of frames per second (FPS) to over 1 million FPS. Depending on the resolution requirement, RMD can engineer the imager to provide relatively smaller, 2.5 x 2.5 cm2, to very large, 1 meter x 1 meter, active area. Key technology enablers are:

1. RMD’s HSSTM scintillation screens that provide fast and bright, afterglow-free emission, high X-ray absorption, and high spatial resolution (Figure 1)
2. Novel X-ray sources designed for specific application, including battery operated multiple pulse sources (Figure 2), that can generate 50 ns X-ray bursts, and
3. Camera optics tailored for efficient light collection. An imager installation and tests at the AFB facility are illustrated in (Figure 3)
