Abstract. Consequence of two methods of processing a photomultiplier output is considered, related to the variance of the estimates obtained. Detection of a radiation producing in the average less than one photoelectron per radiation intensity correlation time is presumed. Distinction between the variance of the respective estimates proves to become greater as pulsations of the light intensity grow.

Keywords:  detection of weak light, light intensity statistics.
