A method of measuring scintillation of two laser beams propagating along single and folded optical paths has been devised, tested, and satisfactorily utilized. The system was utilized experimentally to verify theoretical predictions of the correlation of the two paths as a function of the relative path geometry. The apparatus utilized alternating optical pulses from the two paths. The detection system employed two signal processing channels wtih electronic switching to permit sampling alternating source pulses with a time separation of 0.30 miliseconds. Several equipment trials and one field experiment were conducted. The results demonstrated good correlation with the theory previously developed in an accompanying project
