“…Comparators can have errors due to jitter, long term and short term drift, and variation in the shape and amplitude of the input pulse [186]. This can be compensated for by 1-D techniques such as linear or logarithmic compensation or 2-D compensation techniques like artificial neural networks and polynomials [187,188]. Time resolution is determined with the full width half maximum of the time spectrum [189].…”

Silicon photomultipliers (SiPMs) offer advantages such as lower relative cost, smaller size, and lower operating voltages compared to photomultiplier tubes. A SiPM’s readout circuit topology can significantly affect the characteristics of an imaging array. In nuclear imaging and detection, energy, timing, and position are the primary characteristics of interest. Nuclear imaging has applications in the medical, astronomy, and high energy physics fields, making SiPMs an active research area. This work is focused on the circuit topologies required for nuclear imaging. We surveyed the readout strategies including the front end preamplification topology choices of transimpedance amplifier, charge amplifier, and voltage amplifier. In addition, a review of circuit topologies suitable for energy, timing, and position information extraction was performed along with a summary of performance limitations and current challenges.

The hybrid photodetector (HPD) is a photomultiplier tube combined with the semiconductor device within the vacuum. The photoelectrons emitted from the photocathode directly hit the semiconductor enabling efficient electron multiplication with low noise and symmetric output pulse. These properties make a hybrid photodetector a good solution for photon-counting applications. At the Satellite Laser Ranging Station of the Institute of Astronomy at the University of Latvia, the hybrid photodetector characteristics were evaluated for SLR applications, including multiphoton mode and time-walk compensation.
