  • Solid-state photomultiplier module with improved signal-to-noise ratio
    Patent number: 8222589
    Abstract: A scanning imaging system is provided. The scanning imaging system comprises an illumination source for illuminating a sample with an excitation light, a filter to block emission light wavelengths from the illumination source. Further, the scanning imaging system comprises a SSPM module comprising a solid state photo multiplier to detect a photon flux and generate electrical signals based on impinging photons; a conditioning circuit to accumulate charge from the SSPM and a micro-controller to change a bias voltage applied to the SSPM to achieve a higher signal-to-noise ratio.
    Type: Grant
    Filed: May 29, 2009
    Date of Patent: July 17, 2012
    Assignee: General Electric Company
    Inventor: Gin-Chung Jimmy Wang
  • Solid-state photomultiplier having improved timing resolution
    Patent number: 8110806
    Abstract: A solid-state photomultiplier is provided for use in imaging detectors. The solid-state photomultiplier includes a plurality of microcells configured to detect impinging photons. Each of the plurality of microcells further includes a photodiode coupled to a common electrode through a quenching resistor and configured to convert the impinging photons into electrical signals, and an impedance device coupled in parallel with the quenching resistor so as to reduce overall quenching impedance at high frequency. Further, techniques are provided for implementing low impedance device with controllable value to the SSPM for optimized timing resolution.
