Detector of Optical Vortices as the Main Element of the System of Data Transfer: Principles of Operation, Numerical Model, and Influence of Noise and Atmospheric Turbulence
Figure 6
Calculated over 100 realizations, mean and maximum values of obtained with different topological charges for angles of rotation (a) and (b). Here is Fried’s coherence length. Horizontal dashed lines in the upper and lower parts of the pictures show the regions where values of are greater and lesser than 1.84 and 0.16. In the middle part of Figure 5(a) dashed lines correspond to with threshold values and ; in Figure 5(b) they correspond to with threshold values and . Vertical dashed lines in Figure 5(a) show values of equal to 0.26 and 0.30, while in Figure 5(b) equal to 0.22, 0.25, 0.30, 0.43, and 0.71.
