Abstract
The general problem of the statistical fluctuations in the detection of light quanta by photocells is considered. The various methods of detection of the photoelectric current are compared and the extent to which each method approaches the limiting sensitivity is discussed. It is shown that light intensities of the order of 1 quantum per second can be detected with present apparatus.Keywords
