Abstract
This paper discusses a type of x-ray camera designed to generate standard RS-170 video output that does not use x-ray or optical image intensifiers. Instead, it employs a very sensitive, very high resolution CCD sensor which views an x-ray-to-light conversion screen directly through a high speed imaging lens. This new solid state TV camera, which is described later, has very low readout noise plus unusually high gain which enables it to generate real-time video with incident flux levels typical of many inspection applications. Perhaps more important is an ability to integrate for multiple frame intervals on the chip followed by the output of a standard, RS-170 format video frame containing two balanced interlaced fields. In this integrating mode excellent quality images of low contrast objects can be obtained with only a few tenths of a second integration intervals. The basic elements of this type of camera are described and applications discussed where this approach appears to have important advantages over other methods in common use.
