Paper Abstract

The advantages of a photon counting scheme over a current measuring scheme in the case of a single point or zero dimensional detector is obvious. For a current measuring scheme the circuit noise introduces more and more error as the light level goes down and any error in determination of the circuit gain shows up as an error in the luminosity measurement. On the other hand, photon counting schemes are immune to circuit noise as long as there is a good pulse height distribution, and an error in determination of the gain of the circuit has no effect on the error in the measurement. The error instead is set by the laws of statistics so that the accuracy approaches the ultimate and depends only on the number of photons detected.
