X-Ray Sensitive Imaging Camera

March 25, 2008


The Shad-o-Box 1024 Hi-Res is an X-ray sensitive imaging camera that uses the company’s RadEye X-ray specific digital image sensor. The camera has a 14-bit output and parallel digital interface (LVDS) for direct input to a digital frame grabber. Total power dissipation is less than 6 watts. The 49.2-millimeter by 49.2-millimeter sensing area consists of a 1,024 by 1,024 pixel CMOS photodiode array imager with pixels on 48-micrometer centers. The active area is obtained without the need for an optical interface. A Gd2O2S scintillator screen placed in direct contact with the photodiode array converts incident X-rays or energetic particles to visible light, which in turn is detected by the photodiode imager. Two models cover the energy range from 10 kilovolts to 160 kilovolts.
