What Are the Challenges in Single Photon Counting?
Despite its advantages, single photon counting comes with several challenges:
Dark Counts: These are false counts that occur even in the absence of incident photons. Reducing dark counts is critical for improving the accuracy of measurements. Timing Jitter: This refers to the uncertainty in the timing of the detected photon event. Minimizing timing jitter is essential for applications requiring precise time-resolved measurements. Detection Efficiency: Achieving high detection efficiency is crucial for reliable single photon counting. Different detectors offer varying levels of efficiency, which can impact the overall performance of the system.
