State-of-the-art CMOS Linear Diode Array Detector Boards
X-Scan Imaging Corporation manufactures a family of single-chip, buttable CMOS silicon linear diode array (LDA) detectors 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 photo-diode 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 detector series 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. It is designed to permit end-to-end butting on a printed circuit board to form a single longer detector array for extended length scanning applications.
