ATMOSPHERIC EFFECTS ON DIGITALLY MODULATED LASER TRANSMISSION

Abstract

This investigation has provided data which allow the evaluation of the laser as a transmission device for digital information. In particular, the effect of the atmosphere on laser propagation, modulation, and communication capabilities pertinent to tactical applications has been studied. These studies were made under varying conditions of weather, path length, optical power, modulation depth and modulation method. The characteristics of interest in each case was the bit-error rate obtained with binary serial bit streams. From this information, the operation of a laser PCM system may be forecast.
