XB Series CMOS X-Ray Line Scan Detector Boards

CMOS Photodiode Detector Array; Pixel Size 0.04x0.075 to 1.565x2.4 mm; Resolution 0.05-1.6 mm; 32-6,144 Pixels; Length 51.2-307.2 mm; Scintillator GOS:Tb, CsI:Tl, CdWO4, Other; Data Rate 1 MHz Max.; Dynamic Range >4000

X-Scan Imaging’s XB series are single-chip, buttable silicon CMOS line scan detector boards with on-chip, fully integrated signal processing circuits designed for visible wavelength and x-ray imaging applications.

A scintillator layer is attached to the surface of the photodiode detector array, which converts X-ray photons into visible light. A variety of standard x-ray sensitive scintillator materials are available for applications in industrial inspection, airport security and cargo screening.

Each XB series detector board is configured as a contiguous linear array of photodiodes including a timing generator, digital scanning shift register, an array of charge integrating amplifiers, sample-and-hold circuits and signal amplification chain.

XB series detector boards are designed to permit end-to-end butting on a printed circuit board to form a single longer detector array for extended length scanning applications.
