dc.description.abstractAtmospheric turbulence gives rise to noise in an optical communication system. Processing of the detected signal is necessary for an optimum estimate of the message. Prior knowledge of the statistics of the turbulence-induced noise is desirable. Consideration is given in this work to determining the spatial correlation and the probability density and distribution functions of the laser beam intensity fluctuations in the receiver plane. Two systems have been devised for the purpose of measuring the spatial correlation. An analog crosscorrelator has been built and a digital computer programed to correlate the detected signal. A comparison is made between the two results. Also, the power density spectrum has been evaluated. The results of the measurements are reported and conclusions on the effects of atmospheric parameters on the detected signal are drawn.
