  • Radiation hard visible light readout circuit
    Patent number: 4659930
    Abstract: A pair of photodetectors are electrically connected in series. A common interconnection point of the two photodetectors is electrically connected to the inverting input of an opertional amplifier to provide a signal indicative of visible light falling on one of the photodetectors. The other of the photodetectors is masked to block visible but allow a response to non-visible radiation in the form of gamma, x-rays and the like.
