Optical Scintillation on Folded Paths.
Abstract
Optical scintillation on folded paths has been investigated for the case of spherical waves and a plane mirror as a folding target. A criterion for the statistical independence of the two parts of the folded path was formulated, utilizing the path integral technique and the Von Karman spectrum. Employing the same approach, an expression for the scintillation strength (the log-intensity variance) on folded paths has been developed. It has been shown that the scintillation strength on folded paths can be expressed as a product of the one-way scintillation strength and a function of the distance source-detector in units of the outer scale. The analytical prediction shows that the ratio of the log intensity variances on the folded paths to the one on the one-way path, goes from 2 superscript (17/6), for exact folding (the distance source-detector is zero), to 2 superscript (11/6) when the detector is far away from the source. The theoretical predictions have been corroborated by preliminary field experiments.
