Nomadics proposes the development of an x-ray system for use underwater. The proposed sensor is similar to a raster or "flying spot" backscatter imager. These systems operate by scanning an x-ray beam across a surface and monitoring the backscattered energy. There are two significant challenges to this process, first the system has to operate in an incredibly attenuating environment; second, that environment scatters a large portion of the incident energy before it ever reaches the target. With these two design limitations, Nomadics' believes that the key to building a successful Autonomous Underwater X-Ray system (AUXRAY) is to have a large detector area for sensitivity and separation between the source and detector to reject signal from the transiting x-ray beam.
