Abstract:
A smart sensor for maintaining constant gain in a photosensor despite temperature is disclosed. The smart sensor receives temperature data from a temperature sensor, then compares the temperature data to a lookup table of temperatures corresponding to voltages which, when applied to a photosensor at that temperature, will produce a desired gain. The smart sensor then applies the voltage from the lookup table to the photosensor, to yield a desired gain from the photosensor. The smart sensor is particularly applicable to SiPMs used in PET/MRI imaging systems.
