Photon counting is a technique in which individual photons are counted using a single-photon detector (SPD). A single-photon detector emits a pulse of signal for each detected photon. The counting efficiency is determined by the quantum efficiency and the system's electronic losses. Many … See more Photon counting eliminates gain noise, where the proportionality constant between analog signal out and number of photons varies randomly. Thus, the excess noise factor of a photon-counting detector is unity, and the … See more Single-photon detectors are typically limited to detecting one photon at a time and may require time between detection events to reset. Photons that arrive during this interval may not be detected. Therefore, the maximum light intensity that can be accurately … See more • Single-photon source • Visible Light Photon Counter • Transition edge sensor • Superconducting nanowire single-photon detector See more Single-photon detection is useful in fields such as: • Fiber-optic communication • Quantum information science See more The number of photons observed per unit time is the photon flux.
