Accuracy Characteristics Of Space Optical Communication Systems In Photon Counting Mode

Abstract

The characteristics of optical communication system the type “Space-to-Earth” are investigated. Analytical results for the signal-to-noise ratio for photon counting regime depending on signal registration time intervals are obtained. Expressions describing strong influence of inertia of the photon counting system over dependencies of characteristics of the system from the link range were taken out. Numerical examples, illustrated by graphic material, have been shown.
