“…Substitute Equations ( 7) and (10) for Equation ( 6), and ∆ J is calculated. We assume that the field of SMF could transfer backwards to the pupil plane of the receiving telescope, at which the coupling is processed and in which the condition of the CE is defined by Equations ( 11) and ( 12).…”

“…However, with the increase of theoretical discussion and experimental research [7][8][9], it has been found that Kolmogorov's theory could not always describe the characteristics of actual turbulence, and the non-Kolmogorov turbulence model has been widely applied to evaluate the performance of FSO terminals. Linyan Cui studied the influence of moderate-to-strong non-Kolmogorov turbulence on the imaging system based on the atmospheric turbulence modulation transfer function [10]. Yahya Baykal investigated the behavior of the coherence length in non-Kolmogorov satellite links [11].…”

Non-Kolmogorov turbulence has been widely observed in free-space optical communication links and should be used to evaluate the system performance. We calculated the wavefront residual variance in the condition of the non-Kolmogorov turbulence model and deduced the mathematical expression of the probability density function (PDF) for the coupling efficiency (CE) of a single-mode fiber (SMF). The PDF was simulated, and the results showed its robustness and rationality. Moreover, an experiment was set up to verify the PDF with experimental distribution. The correlation coefficients are above 0.95 in all cases, which means the statistical model of the CE fitted the experimental distribution well.

“…Most of the research analyzed the degree of image degradation focused on the modulation transfer function (MTF). The turbulence effect on the degradation of MTF has been covered in many papers [1][2][3][4][5], including imaging systems in both homogeneous and inhomogenous media. They found that MTF is related to second-order statistics of the field.…”
