  • Large-area detector
    Publication number: 20060175529
    Abstract: A solid state photodetector is disclosed comprising a multiplicity of photodetector elements, each element using clamped Geiger mode gain to achieve high sensitivity and high speed. The elements are connected together using a common anode to sum their outputs, allowing operation with gray-scale response over a large total photosensitive area. In the preferred embodiment, high speed performance is achieved by isolating each element from the bias supply by means of an integrated series resistor.
