Paper Abstract

Correlation of bifrequency beam propagating in a folded turbulent atmospheric path reflected by plane mirror is analyzed and a theoretical expression of correlation coefficient is developed by using Kolmogorov turbulence model in this paper. It is noted that in this optical path the greater the difference between two frequencies is, the worse the correlation will be. The correlation coefficient for folded path is larger than that for direct path when the Fresnel parameter becomes smaller than a certain value and vice versa. The aperture averaging effect has the same characteristics.
