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 2

Influence of phase and amplitude noise with amplitudes 𝐴_𝑛𝑆 and 𝐴_𝑛𝐴 on the probability density of the intensity 𝐼_𝑟 with Δ=180^∘ and 𝜑=0. The vertical dashed line corresponds to 𝐴_𝑛𝑆=0.72𝜋, while horizontal dashed lines correspond to relative intensity 𝐼_𝑟 equal to 0, 1, and 2.
