===== The Pile-Up effect describes the effects of photons lost at high photon count rates due to the dead time of the TCSPC devices. Most single photon counting detectors and [[TCSPC]] electronics have a [[dead time]]. After registering one photon the device needs some time to be ready for the ne

The markers are used to synchronise the photon events with a scanning process allowing to sort the photons into image pixels.
